Performance Analysis of DWMT Transceiver for ADSL Channel with Overlap FDE in Presence of AWGN, Crosstalk and Impulse Noise

Arsla Khan, Sobia Baig, and Soo Y. Shin
Abstract—Discrete wavelet Multi-tone (DWMT) was proposed to overcome the problems of Discrete Multi-tone (DMT) for wireline channels. DWMT based system poses more resistance against inter-symbol interference (ISI) because of tight filters and more spectral efficiency due to absence of cyclic prefix as compared to DMT based system. However, no equalization technique has been standardized yet for DWMT transceiver. In this paper, we are proposing Overlap frequency domain equalization (FDE) for DWMT transceiver for ADSL channel in presence of additive white Gaussian noise (AWGN), crosstalk and impulse noise (IN). From simulations results, we can analyze that Bit error rate (BER) performance of Time domain equalization (TDE) is comparable with Overlap FDE but the main advantage lies in lower computational complexity.

Index Terms—ADSL, AWGN, DMT, DWMT, FEXT, impulse noise, NEXT, overlap FDE.
