A molecular-wire crossbar interconnect for signal routing and communications between a first level and a second level in a molecular-wire crossbar is provided. The molecular wire crossbar comprises a two-dimensional array of a plurality of nanometer-scale switches. Each switch is reconfigurable and self-assembling and comprises a pair of crossed wires which form a junction where one wire crosses another and at least one connector species connecting the pair of crossed wires in the junction. The connector species comprises a bi-stable molecule. Each level comprises at least one group of switches and each group of switches comprises at least one switch, with each group in the first level connected to all other groups in the second level in an all-to-all configuration to provide a scalable, defect-tolerant, fat-tree networking scheme. The primary advantage is ease of fabrication, because an active switch is formed any time two wires cross. This saves tremendously on circuit area (a factor of a few times ten), since no other wires or ancillary devices are needed to operate the switch or store the required configuration. This reduction of the area of a configuration bit and its switch to just the area of two crossing wires is a major advantage in constructing a defect-tolerant interconnect network.

A route to the fabrication of electronic devices is provided, in which the devices consist of two crossed wires sandwiching an electrically addressable molecular species. The approach is extremely simple and inexpensive to implement, and scales from wire dimensions of several micrometers down to nanometer-scale dimensions. The device of the present invention can be used to produce crossbar switch arrays, logic devices, memory devices, and communication and signal routing devices. The present invention enables construction of molecular electronic devices on a length scale than can range from micrometers to nanometers via a straightforward and inexpensive chemical assembly procedure. The device is either partially or completely chemically assembled, and the key to the scaling is that the location of the devices on the substrate are defined once the devices have been assembled, not prior to assembly.

Frequency dependent I / Q imbalance in real I / Q filter pairs compensation may be performed using a simple compensation module, placed in the receiver / transmitter chain, with a gain adjustment coefficient and a delay adjustment coefficient. The gain adjustment coefficient may be determined by amplitude measurements conducted at a selected frequency near the center of the band-pass region of the filters. The delay adjustment coefficient may be determined by phase measurements conducted at a selected frequency near the edge of the band-pass region of the filters. Statistical analysis may be used to determine types of real filters that are better suited for the compensation method and to select the test frequencies that should be used.

Examples of DTV signals include the American Television Standards Committee (ATSC) signals, the European Telecommunications Standards Institute Digital Video Broadcasting-Terrestrial (DVB-T) signals and the Japanese Integrated Service Digital Broadcasting-Terrestrial (ISDB-T) signals.

To control lighting and other utilities in buildings based upon occupancy, mountable sensors are used to detect low energy radio frequencies emitted from devices, or tags, worn or carried by occupants. In a demand control system, identification (ID) codes embedded in tags worn by occupants are detected in each room by a tag sensor and may wirelessly communicate to a zonal compiler that determines zonal occupancy. The zonal occupancy count is transmitted to an interface relay that immediately adjusts the intensity and rate of the specific utility. HVAC systems may also be tied into the system to have adjustments made to the intensity and rate of ventilation as done with the lighting in this system. This system has many advantages over current systems such as not being dependent upon movement of an occupant or following the heat signature of an occupant that both may lead to false readings and delay in adjusting the specific building utility to save energy and costs.
