Because of the ability of turbo codes to provide very low bit error rates at low signal to noise ratios, turbo codes have a potential of being used in wireless communication applications. The main objective of this thesis is the implementation of an Iterative MAP turbo Decoder on a digital signal processor, TMS32OC40. Performance of the decoder was tested over an additive white gaussian noise channel and using a binary phase shift keying signalling scheme. In this thesis our Iterative MAP decoding algorithm and its implementation are discussed and simulation results for different encoders are presented
