Performance of Adaptive OFDM transceiver in wireless channels with loading algorithm
Communication rate would be reduced and frequency resources would be wasted if traditional OFDM is applied in wireless multi-path channel. The frequency-selective fading makes each channel of OFDM system have different transmission ability. To assure communication quality under meeting BER, we design a kind of new adaptive loading algorithm in OFDM transceiver which could change the assign of bit and power dynamically according to the channel, and the algorithm is small in calculating amount and more practical. Simulation results show that performance of adaptive OFDM transceiver in wireless channels with loading algorithm was improved.
