Cell terminals in an integrated circuit is interconnected by using multiple layers of conductors that are routed both orthogonally and non-orthogonally to each other. Non-orthogonally routed conductors have slopes that are ratios of non-zero integers which approximate ceratin predetermined angles. The integers in the ratios are chosen from integers generated by sequence equations. The conductors are routed by following grid lines in a grid system comprising both orthogonal grid lines and non-orthogonal grid lines having slopes generated by the sequence equations. Ratios of integers are used to approximate certain angles so that the conductors would intersect the cell terminals located on the fundamental grid intersection points. The conductors in different metal layers form different angles with other conductors in other metal layers based on the slopes of the conductors.

A computer-implemented approach for routing an integrated circuit using non-orthogonal routing is accomplished during two phases: a global routing phase and a detailed routing phase. During global routing, routing indicators, in the form of hint polygons, are added to the integrated circuit layout and strategy lists, that include bias directions and straying limits, are generated for the new wires to be added. The hint polygons and strategy lists are used during detailed routing to aid in placing the new wires. If obstacle conflicts or insufficient space problems prevent the detailed routing of a new wire, then an obstacle resolution portion of global routing is used to resolve the obstacle conflict and / or provide additional space in the integrated circuit layout to route the new wires. Obstacle resolution includes, without limitation, moving or changing layout geometry, changing or add hint polygons, changing the routing strategy by changing the bias direction and / or adjusting straying limits, inserting one or more layer changes, instructing the detailed router to backup and insert a bend, ripping-up and rerouting one or more wires, or routing the wire from the destination connection point. Also, a tight routing approach may be employed to accommodate constructing routing paths in tight layout areas. Object specific design rule checks are employed to increase routing flexibility optimize routing performance. “On-the-fly” design rule checks are performed on portions of routing paths as the routing paths are being constructed.

An advanced channel storage and retrieving system is achieved that is capable of simultaneously transporting multiple-stream data concurrently, with encryptions and error detection and limited correction capability using wavefront (WF) multiplexing (muxing) at the pre-processing and WF demultiplexing (de-muxing) in the post-processing. The WF muxing and demuxing processing can be applied for multiple signal streams with similar contents and format such as cable TV delivery systems or multiple signal streams with very distinct contents and format such as Karaoke multimedia systems. The stored or transported data are preprocessed by a WF muxing processor and are in the formats of multiple sub-channels. Signals in each sub-channel are results of unique linear combination of all the input signals streams. Conversely, an input signal stream is replicated and appears on all the sub-channels. Furthermore the replicated streams in various sub-channels are “linked” together by a unique phase weighting vector, which is called “wavefront” or WF. Various input signal streams will feature different WFs among their replicated signal streams in the sub-channels. The WF muxing processing is capable to generating a set of orthogonal WFs, and the WF demuxing processing is capable of reconstituting the input signal streams based on the retrieved sub-channel data only if the orthogonal characteristics of a set of WFs are preserved. Without the orthogonality among the WF, the signals in sub-channels are mixed and become effectively pseudo random noise. Therefore, an electronic locking mechanism in the preprocessing is implemented to make the WFs un-orthogonal among one another. Similarly, an electronic un-locking mechanism in the post-processing is implemented to restore the orthogonal characteristics among various WFs embedded in the sub-channel signals. Some of the phenomena due to the selected locking mechanisms are reproducible in nature, such as wave propagating effects, and other are distinctively man-made; such as switching sub-channel sequences. There are other conventional encryption techniques using public and private keys which can be applied in conjunction with the WF muxing and de-muxing processor, converting plain data streams into ciphered data streams which can be decoded back into the original plain data streams. An encryption algorithm along with a key is used in the encryption and decryption of data. As to the optional parallel to serial and serial to parallel conversions in the pre and post processing, respectively, we assume that transmissions with single carrier are more efficient than those with multiple carriers. We also assume single channel recording is more cost effective than multiple channel recording. However, there are occasions that continuous spectrum is hard to come-by. We may use fragmented spectrum for transmissions. There are techniques to convert wideband waveforms using continuous spectra into multiple fragmented sub-channels distributed on non-continuous frequency slots. Under these conditions we may replace the parallel to serial conversion processing by a frequency mapping processor.

Provided are a receiver, a transmitter and a radio communication method capable of using non-orthogonal multiple access while suppressing cost increase and processing delay. A mobile station 200A receives non-orthogonal signals, also receives a reference signal to be used for interference cancellation, and extracts the non-orthogonal signal addressed to the mobile station 200A from the received non-orthogonal signals by demodulating and cancelling the radio signal addressed to another mobile station. In addition, the mobile station 200A demodulates the extracted non-orthogonal signal addressed to the mobile station 200A on the basis of the reference signal. The reference signal is multiplexed in the same radio resource block as a resource block allocated to the non-orthogonal signals, and is multiplexed in the radio resource block only when at least one signal is scheduled in the radio resource block.

Fiber optic transmitter and receiver electrical elements are implemented on separate vertical boards in fiber optic modules. An optical block implements lenses and reflecting surfaces to minimize manufacturing costs. The light receiver and light transmitter are mounted to receive and transmit non-orthogonal to the fiber axis to avoid optical cross talk. In one embodiment, receiver and transmitter are mounted at an angle greater than forty-five degrees with a perpendicular line to the reflective surfaces. In another embodiment, receiver and transmitter are mounted at an angle less than forty-five degrees with a perpendicular line to the reflective surfaces. The reflective surface for transmission may be a beam shaper to improve light beam uniformity and optical coupling and to avoid active alignment. The vertical boards have ground planes facing each other to minimize electrical cross talk. An optional shielded housing provides further shielding for reducing EMI.
