Adaptive local wireless communication system

A radio link management system for a home or office substantially (i) an ad hoc network of agents wirelessly communicating among themselves, while (iii) clients wirelessly communicate with proximate agents. Control of the network may be centralized as network controller integrated with an agent, or may be distributed upon the network of agents. Some agent or agents, which may include an agent that is also the network controller, typically serves as a gateway device which connects to a worldwide communications network external to the home or office, normally by fiber or by wire.Each agent is most commonly a small radio transceiver plus logic and power supply that mounts upon a wall and plugs directly into an AC power socket. Agents wirelessly communicate among themselves and with the controller—which may be centralized or distributed—in a bandwidth-efficient mode since prime power is not an issue. Each client, which is most commonly a battery-powered user device, wirelessly radio communicates with one or more proximately-located agents. Consistent with overall demand for the radio resource, parameters for radio communication are allocated ad hoc in a manner which is (a) client-dependent, and which (b) uses the least power from the battery-powered client. The agents establish an ad-hoc network among themselves, with routing among and between the agents being both multi-hop and “minimum hop” to conserve bandwidth. Accordingly both power and bandwidth are conserved, each as and where required and desired.

Active audio noise cancelling

A noise canceling system comprises a microphone (103) generating a captured signal and a sound transducer (101) radiating a sound canceling audio signal in the audio environment. A feedback path (109) from the microphone (103) to the sound transducer (101) comprises a non-adaptive canceling filter (115) and a variable gain (117) and receives the captured signal and generates a drive signal for the sound transducer (101). A gain detector determines a secondary path gain for at least part of a secondary path of a feedback loop. The secondary path may include the microphone (103), the sound transducer (101), and the acoustic path therebetween but does not include the non-adaptive canceling filter (115) or the variable gain (117). A gain controller (121) adjusts the gain of the variable gain (117) in response to the secondary path gain. The system uses simple gain estimation and control to efficiently compensate for variations in the secondary path to provide improved stability and noise canceling performance.

Dynamic quality adjustment based on changing streaming constraints

InactiveUS7512698B1Reduces streaming constraintEliminating waste in bandwidthDisc-shaped record carriersRedundant array of inexpensive disk systemsClient-sideComputer science
A method and apparatus for dynamic quality adjustment of digital media based on changing streaming constraints is provided. A digital media server sends a digital media stream according to a set of streaming constraints to a requesting client. Audio and visual information may be sent to a requesting client together in a single stream, or separately in multiple streams. A client sends a request over a control network to the digital media server indicating information of a particular type is no longer desired. In response to receiving the signal, the video server ceases transmission of that particular type of information to the signaling client, thus relaxing streaming constraints. As a result of the techniques described herein, an improved quality digital presentation is available for the client and, consequently, when a viewer signals that a particular type of information is not desired, that particular type of information is not transmitted to the client, which thereby reduces the streaming constraints on a video streaming service, and improved quality digital media information may be sent to any client using the freed-up portion of the bandwidth previously allocated to the signaling client.

Systems and methods that employ a balanced duplexer

The present invention relates to systems and methods that employ a novel balanced duplexer that can be utilized to facilitate concurrent signal transmission and reception. The systems and methods can be employed within mobile devices such as cell phones and utilize two-filters (e.g., acoustic) with substantially similar input / output impedances interfaced with two couplers (e.g., 3 dB hybrid), which provide isolation and maintain the duplexer's input / output impedance. The couplers interface the filters to front / back ends such as signal processors, transmitters and receivers. The novel aspects of the present invention mitigate the need to employ external directional couplers between the duplexer and front / back ends. In addition, the two-filter topology enables employment of lower powered rated filters. The systems and methods further provide for separation and isolation of transmitters and receivers, which reduces noise coupling and enables the transmitter and receiver to be placed within close proximity.

Method of rate matching for link adaptation and code space management

A method of symbol combining and incremental redundancy for link adaptation and code space management was proposed. In order to reduce constraints on the Walsh codes allocation, MCS level change, as well as frame duration change for the initial transmission and re-transmissions, a “rate matching” stage is proposed between the Turbo encoder and block interleaver on the transmitter. In the initial transmission, the Turbo encoded symbols are interleaved with or without any puncturing or repeating (i.e. puncture / repeat factor is set to 1). The coded symbols are also stored in the memory for possible retransmissions. In the re-transmission, the transmitter first determines the number of Walsh codes available for this user and MCS level and frame duration according to the C / I feedback values from MS. The stored coded symbols are then punctured or repeated according to “rate matching factors”. On the receiver side, “rate matching factors” can be derived from the number of code channels, MCS level and frame duration of current re-transmissions and initial transmission. Then, de-puncturing / de-repeating is performed before coded symbol combining. A similar rate matching based IR / symbol combining scheme can be used to design different IR using different rate matching algorithms. It has low implementation complexity and is easily made backward compatible.
