Abstract :
Two retransmission request mechanisms for trellis coded modulation systems are compared. The first scheme is a one-code system based on an algorithm developed by Yamamoto and Itoh. The second is a two-code system that uses CRC codes for error detection. It is shown that the two-code system is almost always the preferable approach.
