【 摘 要 】

In this letter, the performance of the HIPERLAN system (GMSK with BT=0.3) is considered, in the presence of indoor multipath fading channels. Due to the high carrier frequency and high data rate, a simple noncoherent demodulator followed by a nonlinear equalizer, which includes a RAM and a Viterbi decoder, is proposed to cope with intersymbol interference. The novelty of the proposed equalizer is that a complex noncoherent signal is used. Although the complexity of the receiver is doubled, performance is greatly improved with respect to real receivers. 3 Pages
