Turbo-coded OFDM with PACE Here we will discuss the results of our proposed model of OFDM implemented with turbo codes and with the aid of Pilot-assisted Channel Estimation. e. SUI channel model-4. The basic aim of the upcoming results was to show the impact of the changing number of iterations of the Maximum a-posteriori decoding algorithm on the performance of the proposed model.
