Prototype of channel coding algorithms for digital signal processing board

This paper presents a prototype of the channel coding algorithms with a baseband modem for TMS320C6713 implementation purpose. It is essential to use channel coding in baseband signal in order to reduce the error of the received signal. In this study, convolutional code (CC) is selected to be the type of channel coding and Viterbi decoder for decoding method. The parameters that have been analyzed in the research are constraint length, modulation techniques and decoding decision. The baseband modem with channel coding is simulated in Additive White Gaussian Noise (AWGN) and the performances of each parameter are compared in terms of Bit Error Rate (BER) with theoretical values. Results from the simulation of the proposed baseband modem are in line with the theoretical results. The successful in uploading process for the baseband modem model into TMS320C6713 DSP Starter Kit (DSK) indicates the model is suitable for implementation purpose and further improvements need to be made in the next research in order to validate the implementation results.
