Patent ID: 8121205

Claim:
A method of transmitting a data stream S(i) across an electrical serial channel in an electronic system at a first rate of R symbols/sec, the method comprising: partitioning the data stream S(i) into N data sub-streams S j (k), by supplying N symbols, S(kN+j) for 0≦j≦N, to a joint coder during a first coding time, and then, for each value of j, supplying symbol S(kN+N+j) to the joint coder instead of symbol S(kN+j) at coding time separated from the first coding time by j/R seconds, where N>2 and 0≦j≦N; and transmitting the N data sub-streams S j (k) concurrently on the electrical serial channel by supplying, from each data sub-stream, one symbol to the joint coder, the joint coder transmitting an NRZ signal representing the sum of the symbol, wherein each data sub-stream is transmitted using Non-Return-to-Zero (NRZ) signaling at a data rate of R/N symbols/sec, the symbol transitions on the N data sub-streams are staggered in time such that a symbol transition on data sub-stream S j (k) is separated from a symbol transition on data stream S j+1 (k) by 1/R seconds.
