Abstract
The integrity of received data is a critical consideration in the design of digital communications and storage systems. The technique involved in attaining data reliability while transmission over a wireless channel is to use Channel Coding. These coding methods involve the use of Error Control Codes and there are two basic ways of controlling errors. They are Automatic Repeat Request and Forward Error Correction. This thesis concentrates on Forward error correction that deals with error detection and error correction. There are two types of error control codes: Block Codes and Convolutional Codes. The extent to which the errors are detected is a measure of the success of the code. The main trade-off in the error correction/detection technique lies in the key parameters involved in evaluating a coding system. Various block codes are analyzed using the performance metrics, namely, Improvement ratio and Error Resilience. It is observed that Cyclic Redundancy Check (CRC) codes showed better performance, and hence, they are chosen for further study.
