Kalman Filter Based Approach of a signal by removing ICI for OFDM Channel

Abstract— This paper deals with the case of a high speed mobile receiver operating in an orthogonal-frequency division multiplexing (OFDM) communication system. The OFDM communication is very much inspired from the channel frequencies over the network. In such network some kind of orthogonal distortion occurs over the channel called Inter carrier Interference. Here we will improve the ICI using Kalman Filtering improved by using repetitive slot and correlated channel tap. The proposed work of this paper is when data travel over some channel it suffers from the problem of interference. The interference results the high signal to noise ratio as well as high bit error rate. The proposed system will improved the signal by removing the different kind of impurities over the signal. These impurities include the ICI, PAPR and the noise over the signal. The signal will be more effective than standard OFDM. So we needn't many pilot symbols in practice, still can ensure the algorithm performance and reduce the time- delay and complexity of this algorithm
