ABSTRACT:
Digital information is convolved with a pseudorandom code and then transmitted at radio frequency in a spread spectrum signal to a receiver also containing the same pseudorandom code. Since the transmitted signal is below the noise floor for that bandwidth, it is virtually unjammable and undetectable without possession of the pseudorandom code. Successful extraction of the transmitted information depends upon precise matching of the transmitted frequency and the exact phase matching of the pseudorandom code at the receiver with the convolved pseudorandom code in the transmitted signal.
