Aspects of Coding and Modulation for OFDM

Overview The channel capacity of some ISI channels is examined under the condition that OFDM in conjunction with QAM modulation for subcarriers and the BICM coding scheme is used. The combination of higher order modulation schemes and low rate codes yields results relatively close to the optimum possible solution, even without application of water-filling and/or bit loading. Simulations with a turbo coded OFDM system confirm the results.
