Abstract:
In this paper, a time division duplex(TDD)multicarrier system based on Nyquist filter bank is proposed for wireless broadband communications. In this system a novel two-tap pre-equalizer is adopted to effectively suppress the inter-symbol interference(ISI). Studies show that the system has almost the same frequency spectrum efficiency as the orthogonal frequency division multiplexing(OFDM)system. Simulation results show that the proposed system outperforms the conventional OFDM system with one-tap maximum likelihood equalizer(MLE)in low signal-to-noise ratio(SNR)and is quite robust to carrier frequency offset.
