An Equalization Technique for OFDM Systems in Fast-Fading Multipath Channels at Low SNR Bin SHENG Yuying ZHOU Xiaohu YOU Publication IEICE TRANSACTIONS on Communications Vol.E89-B No.2 pp.618-620 Publication Date: 2006/02/01 Online ISSN: 1745-1345 DOI: 10.1093/ietcom/e89-b.2.618 Print ISSN: 0916-8516 Type of Manuscript: LETTER Category: Wireless Communication Technologies Keyword: OFDM, equalization, channel estimation, Rayleigh fading, Full Text: PDF(194.8KB)>>
Summary: In this letter, a novel channel estimation method is proposed for frequency-domain equalization of OFDM systems in fast fading multipath channels. It is shown by computer simulations that the proposed method can not only estimate the channel impulse response (CIR) accurately but also achieve lower BER than conventional method at low signal-to-noise ratio (SNR). | |||||
