Abstract :
Adaptive OFDM technology is the real-time response of the transmitter according to the time-varying channel, it has been widely applied to wireless channels with multi-path interference to build high-speed, reliable communication links. At present, Campello algorithm should be the relatively outstanding adaptive OFDM algorithm in comparison, but it needs a great amount of computation. Hence, we proposes an improved scheme of low-complexity based on Campello algorithm in the paper. Simulation results show that the improved algorithm is close to Campello in performance, but the complexity is improved obviously.
