摘要
Abstract
Equalization methods are unnecessary for differential modulation OFDM in slowly varying channel. When the channel varies drastically, the bit error rate (BER) will be aggravated. Due to no pilot in differential modulation OFDM, the equalization methods using pilot signal can not be used in differential modulation OFDM. A channel equalization method suitable for mobile TV/mobile multimedia broadcasting systems is proposed in the paper. Cepstral technique is employed in the method to attain the channel equalization. The simulation results indicate that this method has a favorable equalization effect关键词
