Abstract :
An algorithm for mapping between information bits and channel symbols in multiple trellis-coded modulation (MTCM) codes with M-PSK signal sets is proposed. The core of the algorithm assigns information bits with a Hamming distance in proportion to the sum of the Euclidean distance to each M-PSK symbol. The analytical results show that the additional gains from applying the algorithm can be achieved with little or no loss
