Abstract

Orthogonal Frequency Division Multiplexing (OFDM) has recently been applied in wireless communication systems due to its high data rate transmission capability with high bandwidth efficiency and its robustness to multi-path delay. Fading is the one of the major aspect which is considered in the receiver. The main objective is to transmit the data with low bit error with error free transmission. rate in the noisy environment. To cancel the effect of fading, channel estimation and equalization procedure must be done at the receiver before data demodulation. In this paper, Modified iterative – linear minimum mean square error (MI-LMMSE) estimators are suggested and bit error rate (BER) & mean square error (MSE) performance has been analyzed. Channel estimation modified iterative linear minimum mean square error (MI-LMMSE) algorithm is also integrated with CC-OFDM system and presented with modified iterative NLMS algorithm (MI-NLMS) in terms of convergence rates analysis. The performance of proposed algorithms is analyzed in terms of BER, SNR, and MSE.
