Patent ID: 8320408

Claim:
A multi-channel signal system, comprising: a plurality of code modulators for receiving a plurality of input signals, wherein each code modulator modulates with a unique code one of said plurality of input signals to output a code-modulated signal; a signal summer coupled to each of said plurality of code modulators that combines the code-modulated signals into a combined signal; a shared processing block coupled to the signal summer for processing the combined signal; a plurality of matched filters coupled to the shared processing block, wherein each matched filter includes a code corresponding to one of the unique codes for recovering the corresponding input signal from the combined signal; an initial sample-and-hold block that sequentially samples and holds a single input channel and outputs one of N number of samples of the single input channel to each of N number of delay blocks, coupled to said sample-and-hold block; wherein the n-th delay block delays the multiplexing process of its output sample by N−n clock cycles; and wherein said plurality of delay blocks output the plurality of input signals for receipt by the plurality of code modulators.
