Abstract
An encoder circuit and a related method for its operation, in which digital encoding, such as differential phase-shift keyed (DPSK) encoding, is performed as a parallel operation on N bits at a time. Each encoded bit is both output in parallel with the others of the N bits and is coupled as an input to encode the immediately next bit in the input data stream. The Nencoded bit is fed back to the first encoder stage for use in encoding the (N+1)bit in the input stream. The encoder typically includes a serial-to-parallel converter at the encoder inputs, and a parallel-to-serial converter at the encoder outputs.
