Abstract :
Incremental redundancy transmission is an efficient data communication technique in a frequency hopping code division multiple access system. However, there are some difficulties in practical implementation of this technique such as synchronization of packets of different sizes and identification between regular and subpackets. This paper describes these problems and suggests practical solutions to avoid the loss of synchronization and decoding ambiguity during transmission of messages
