Abstract
A method and apparatus for constructing high rate trellis codes for PSK modulation that can be encoded and decoded using the encoder and decoder for a rate 1/2 punctured convolutional code. In particular, the design of trellis encoders and decoders for 2.sup.k -PSK modulation for rates (km-1)/km for k.gtoreq.3 and m.gtoreq.1 is provided.
