A Low-Complexity Channel Estimation for OFDM Systems Based on CIR Length Adaptation

This paper addresses an adaptive implementation of frequency-domain channel estimators for orthogonal frequency-division multiplexing (OFDM) systems to reduce computational complexity. The linear minimum mean-square-error (LMMSE) estimator provides optimal performance at the cost of high computation...
