Real-time reception of NHS-OFDM signal with SPA-enhanced channel estimation for intensity-modulated direct-detection systems
文献摘要：
In this Letter,we have experimentally verified a low-complexity subcarrier pairwise-averaging[SPA]-enhanced channel estimation[CE]method for small-size fast Fourier transform[FFT]non-Hermitian symmetric orthogonal frequency-division multiplexing[NHS-OFDM]transceivers.Compared with intra-symbol frequency averaging[ISFA],more than 20％look-up tables and 10％logic power consumption can be saved.The least-square[LS],ISFA,and SPA CE methods are compared by offline and real-time digital signal processing approaches.The results show that the receiver sensitivity of the SPA NHS-OFDM transmission system with 64/128-point FFT can be improved by more than 1 dB at the bit error rate of 3.8×10-3 compared to the LS.
