This document summarizes the simulation of a turbo coded orthogonal frequency division multiplexing (OFDM) system. Key points: 1) OFDM divides a wideband channel into narrowband channels to mitigate multipath fading effects. Turbo codes are added to OFDM to improve performance at high data rates. 2) Turbo codes use parallel concatenated convolutional codes for encoding and iterative decoding. Simulation shows turbo coded OFDM outperforms uncoded OFDM with lower bit error rates over both additive white Gaussian noise and Rayleigh fading channels. 3) The simulation model includes a turbo encoder, QAM modulation, IFFT/FFT, channel with noise, turbo decoder. Results show turbo coded OFDM provides much
