Abstract
A neural network is disclosed in which communication between processing elements occurs by radio waves in a waveguide. Radio wave communication using common carrier signals by transceivers in a waveguide allows processing elements to communicate wirelessly and simultaneously. Each processing element includes a radio frequency transceiver and an accompanying antenna which performs the neuron summing operation because input signals simultaneously received from plural processing elements by the antenna add. The weights on each input are provided by different spatial relationships between the transmitting processing elements and the receiving processing element which causes signal strength loses through the waveguide to be different. Each receiving processing element performs a neural threshold or sigmoid operation on the summed signal received from the transceiver and then a strength (amplitude scaling) can be applied to the output before the processing element transmits that output to the other processing elements in the system. Processing elements are grouped, allowing one group to transmit while the other group is receiving. Wafer scale electronics including transceivers and analog processing elements are combined with a comparably sized waveguide to produce a compact device.
