Abstract:
A system for encoding an information signal to produce a resultant output signal comprising:a plurality of code modulators, each code modulator receiving a respective input signal and generating a respective output signal, the code modulators arranged in a series cascade such that the information signal is fed as an input signal to a first code modulator and an output signal of the first code modulator is fed as an input signal to a second code modulator, and wherein an output signal from a final code modulator is used as the respective output signal, and wherein each code modulator further comprises: a channel sequence combiner receiving the respective input signal, and receiving a respective channel sequence, the channel sequence combiner combining the respective input signal with the channel sequence signal to produce a respective combined signal; and a selector coupled to receive the respective input signal, the respective combined signal and a repetitive strobe signal, the selector selecting one of the respective input signal and the respective combined signal to produce the respective output signal based upon a value of the repetitive strobe signal, wherein the repetitive strobe signal is of a length greater than the channel sequence signal.
