Abstract
A codec for resolving transmission phase ambiguities in the M-ary PSK modulation of trellis coded data. A trellis encoder uses a differential encoder and a convolutional encoder, along with multiplexed differential encoders, to generate from sets of input data bits corresponding phase point values for use in M-ary PSK carrier modulation. A trellis decoder uses a Viterbi decoder and a differential decoder, along with multiplexed differential decoders, to produce estimates of the original input data bits from the received signal sector value.
