Distance Properties of Convolutional Codes and Encodersnce structure. The distance properties of a code or an encoder determine its error-correcting and detecting capabilities and are useful in analyzing the performance of various decoding techniques. Many of the distance parameters discussed in this chapter are also useful in selecting good encoders.

Conventional ARQ schemes require a feedback channel to send acknowledgements (positive or negative). Under good channel conditions, the throughput of ARQ schemes is very high, limited only by the r

Variable-Redundancy Error Control Schemesr throughput degrades rapidly as the channel conditions deteriorate. This degradation can be postponed by embedding FEC in the protocol (e.g. hybrid-ARQ) to correct common errors, and by requesting retransmissions only when uncorrectable errors are detected. The net effect of using a more powerful c
