Joint iterative receiver design and multi-segmental channel estimation for OFDM systems over Rapidly Time-Varying Channels

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Rapidly time-varying channels introduce a significantly detrimental effect on conventional OFDM systems, which results in inter-carrier interference (ICI) and degrades the bit error rate (BER) performance, and makes channel estimation more difficult. In this paper, we propose a simple iterative receiver (MF-PIC) with multi-segmental channel estimation (MSCE) to improve the channel estimation and data detection performances over such high mobility scenarios. A matched-filter (MF) with parallel interference cancellation is employed to combat the ICI, and the symbol estimates are fed back for iterative channel estimation (MSCE). Simulation results demonstrate that the proposed receiver design can achieve a better BER performance over a wide range of normalised Doppler frequencies.
