Abstract: The Inter carrier interference (ICI) and inter block interference (IBI) are the two signal degradations on multi user orthogonal frequency division multiplexing (OFDM) communication system. In this paper, a noval methodology is proposed for the detection and reduction of ICI in received OFDM symbols. The vector precoding technique is proposed to reduce the ICI and more bandwidth efficient than other precoding techniques to eliminate ICI. The precoding architecture is used to determine the level of interference in the received OFDM symbols. The proposed interference cancellation architecture is designed and implemented in VLSI for analyzing its low power, bit error rate and energy consumption with conventional methods.
