Product codes are powerful codes that can be used to correct errors or recover erasures. The simplest form of a product code is that where every row and every column is terminated by a single parity bit referred to as single parity check (SPC) product code. This code has a minimum distance of four and is thus guaranteed to recover all single, double, and triple erasure patterns. Judging the code performance based on its minimum distance is very pessimistic because the code is actually capable of recovering many higher erasure patterns. A detailed mathematical analysis has been carried out for erasure pattern of the SPC Product code. We derive a formula for finding the number of unrecoverable basic pattern and the number of recoverable pattern generated from the unrecoverable basic pattern. The post decoding rate is calculated for SPC Product code. Our results are in good agreement with Kousa [1]. Simulation results show that the error correcting capability of the SPC product code is beyond the minimum distance.

Models are developed to analyze the throughput of ARQ protocols, such as Go Back N and Selective Repeat, and protocols without ARQ. Forward error correction is added to these models to study the interactions between these mechanisms.In systems where sending FEC has a negligible effect on the channel loss probability, the goodput of streams increases. Reducing the data throughput and including error correction packets, thus keeping the data rate perceived by the channel constant, has advantages in the Go Back N protocol when the channel loss rate is above a certain range. Furthermore, these models form a starting point with which to study more complicated models such as the TCP.
