正交频分复用调制中的一种时域均衡器
Study on the technique of the time domain equalizer in OFDM systems
摘要
Abstract
A new adaptive TEQ (time equalizer) design for OrthogonalFrequency Division Multiplex (OFDM) demodulation is presented. The TEQ is a simple finite impulse response filter (FIR) used in the receiver for shortening the total length of the effective channel impulse response to avoid using a very long cyclic prefix, so that the simple effective single complex tap per subchannel equalizer can be used. We give a new approach to obtaining the optimal TEQ coefficients fully using the essential property of OFDM modulation. The computer simulation results are also given.关键词
