Abstract
Abstract - In the field of multicarrier system, the leading features such as orthogonal frequency division multiplexing (OFDM) are utilized with various applications. OFDM system performance is affected with some negatives phenomenon such as impulsive noise, high peak to average power ratio (PAPR), deep fading channel, and frequency offset. In the sequel, great efforts are used to solve or reduce the effects of these problems in the recent studies. In this paper, a new multicarrier system is presented that can reduce the major sources of disturbance in OFDM systems that impact on the performance of such systems is impulsive noise. The new proposed system based on using complex hadamard transform (CHT) and a matrix interleaver(MI) with an OFDM. This system achieves a considerable BER performance over maultipath transmission and under disturbance of medium and heavy impulsive noise. The proposed system has computational complexity less than fast Fourier transform (FFT) that is used in conventional OFDM system, also there is improvement in bit error rate (BER) . Keywords - OFDM, Complex hadamard Transform (CHT), Impulse Noise, Discrete Fourier transform (DFT), Matrix Interleaver (MI).
