TY - JOUR ID - TI - High Performance PCC-DMT System Based on Hybrid Multi-Wavelet Functions AU - Hussein Abdel Mohicin Kazem حسين عبد المحسن كاظم PY - 2010 VL - 1 IS - 2 SP - 55 EP - 70 JO - University of Thi-Qar Journal for Engineering Sciences مجلة جامعة ذي قار للعلوم الهندسية SN - 26645564 26645572 AB - In this paper a scheme is proposed to improve the Bit Error Rate (BER) performancefor Discrete Multi-Tone (DMT) system in wireless channel. The conventional DMT system isbased on Fast Fourier Transform (FFT). The proposed system is based on Hybrid Multi-Wavelet Transform (HMWT). The HMWT is mixed between FFT and Multi-WaveletTransform (MWT). The Inter-Carrier Interference (ICI) in DMT system due to Dopplerspread is reduced by using Polynomial Cancellation Coding (PCC). Simulation results aredone in three different types of channels: Additive White Gaussian Noise (AWGN) channel,flat fading channel and selective fading channel. The results show that the PCC-DMT systembased on HMWT achieves better performance than the PCC-DMT system based on FFT andthe PCC-DMT system based on MWT in all channels types.
