Low complexity partial sampled MMSE channel estimation for downlink OFDMA IEEE 802.16e system (original) (raw)

2009 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2009

Abstract

Channel estimation is one of key problems in IEEE 802.16e Orthogonal Frequency Division Multiplexing Access (OFDMA) downlink system. Minimum Mean Square Error (MMSE) channel estimation has been known as a superior performance channel estimation. However, this algorithm has high computational complexity. In this paper, we present low complexity partial-sampled MMSE channel estimation for compromising between complexity and performance. We reduced
