Claim 10:
11. An apparatus for distributing digital samples from one or more input media signals to P electromagnetic paths, said apparatus comprising:
a distributing permuter that distributes said digital samples from said one or more input media signals into P indexed input vectors each of length N, by implementing a predetermined distributing permutation by which each digital sample is distributed to one of said indexes of said input vectors, wherein P is an integer ≥2;
P encoders, each encoder encoding one of said input vectors using N codes of a code set, wherein each code of said code set is associated with one of said digital samples of said one of said input vectors, wherein each of the N codes is an indexed sequence of L chips and each of the N codes is different from and orthogonal to each of the other N−1 codes in the code set, and wherein N and L are each an integer such that L≥N≥2, each encoder performing the following sub-steps for each of L indices on the input vector corresponding to said each encoder in order to form an ordered series of L digital output levels per encoder:
i. modulating each digital sample in an input vector by the indexed chip in said code corresponding to said each digital sample, and
ii. summing the results of all the modulations of sub-step (i) to form one of said ordered series of digital output levels;

a digital-to-analog converter that converts said ordered series of L digital output levels per encoder into an ordered series of L analog output levels per encoder; and
an output terminal for each of the P electromagnetic paths corresponding to one of the encoders that makes available said L analog output levels and outputs said L analog output levels on said each electromagnetic path, wherein said L analog output levels represent said N digital samples of the input vector encoded by the encoder corresponding to said each electromagnetic path.
