Low-Complexity MMSE Channel Estimator for MB-OFDM UWB Systems

Moufida Hajjaj, Fadoua Mhiri, and Ridha Bouallegue
Abstract—Channel estimation is one of the key technologies in multi-band (MB) Orthogonal Frequency Division Multiplexing (OFDM) Ultra Wide Band (UWB) systems, which has received more and more consideration. MMSE channel estimation has been known as superior performance channel estimation. However, this algorithm has high computational complexity. In this paper, a modified MMSE channel estimation for MB-OFDM UWB is proposed. We evaluate the performance of the modified channel estimator in terms of the bit error rate (BER) by computer simulations. It is shown that the proposed channel estimator gives the best tradeoff between performance and complexity.

Index Terms—MB-OFDM, UWB, OLR-MMSE channel estimator.
