Abstract This project builds upon the Viterbi encoding/decoding project from EE517 and the code division multiple access (CDMA) project from EE518 to model end-to-end digital communications. A C++ project was developed that lets the user select a 32 by 32 pixel window of a color bitmap for transmission. The selected pixels are digitized, and the user can choose to encrypt, encode, interleave, and modulate the bits. The user can select the bit error rate (BER), or choose burst errors, which will...

Abstract Bose-Chadhuri-Hocquenghem (BCH) codes belong to a powerful class of cyclic block codes that can be used to improve the performance of a communication link by detecting or correcting errors. BCH codes are considered to be the best of the binary block codes and are commonly used as a Forward Error Correction (FEC) technique in military and commercial communcation systems. Since the discovery of BCH codes, many mathematicians have developed decoding algorithms that can be implemented in...
