Abstract :
Forward error correction (FEC) plays an increasingly important role in today´s communication systems. It will improve the capacity of a channel by adding some carefully designed redundant information to the data being transmitted through the channel. The process of adding this redundant information to the data is known as channel coding. In most wireless communication systems, convolutional coding is the preferred method of channel coding to overcome transmission distortions. This paper discusses the implementation of convolutional coding and Viterbi decoding onto Texas Instruments (TI) TMS320C6711 DSP to improve the FEC performance in terms of its execution time and realtime capability
