OPTIMAL CFO CHANNEL ESTIMATION FOR ADAPTIVE RECEIVER DESIGN

An efficient of the inter carrier interference (ICI) cancellation in the adaptive receiver using orthogonal frequency division multiplexing system by two path conjugate transmission. At the receiver side the phase rotated conjugate cancellation (PRCC) concept is used and only one of the phase rotation is employed on the transmit path and two of the phase rotation is employed on the two of the receiver path.The main objective is to maximize the carrier-to-interference ratio and signal to noise ratio to achieve a high spectral efficiency using the fast least mean square algorithm to improve the bit error rate performance. The carrier frequency offset occurs in the mobile environment due to Doppler effects. Here the OFDM is used because it is highly sensitive to the carrier frequency offset
