Abstract
Methodology, and associated circuitry, for encoding and decoding signals utilize optimizing orthogonal code techniques that effect autonomy of communications and simplified signal processing, thereby improving reliability. Encoder (121) processes an incoming data stream by associating an optimizing orthogonal code with each binary one in the input stream and then by transmitting a series of rate-increased pulses over a path during intervals determined by the code for each of the binary ones. Decoder (131) is generally arranged as a correlation detector in that the decoder only responds to the particular optimizing orthogonal code for which it is configured. Sensors in energy transfer relation to the path are positioned at detection points on the path in correspondence to an assigned code. The outputs of the sensors are processed to produce a rate-decreased detected signal at the rate of the input stream whenever a rate-increased stream corresponding to the decoder configuration is propagating along the path.
