Abstract
In this paper, a minimum mean square error (MMSE) channel estimation technique for an OFDM system with a transparent mobile multi-hop relay (MMR) is proposed by taking into account the effect of propagation delays due to relaying. It is demonstrated by computer simulation that the proposed MMSE channel estimation technique for OFDM systems with cooperative MMR is superior to the conventional technique in terms of the mean square error (MSE) and bit error rate (BER).
