| Abstract: | Adjacent systems within a cable binder that transmit or receive data in the same frequency range can create crosstalk interference. Crosstalk canceller plays a key role in achieving high bit rates in wire line multicarrier Asymmetric Digital Subscriber Line (ADSL) systems. In this paper we propose Recursive Least Square (RLS), Frequency Domain Least Mean Square (FDLMS) adaptive filters and wavelet technique for Near End Crosstalk (NEXT) mitigation to improve signal to noise ratio(SNR) at the input of the receiver which in-turn improves the datarate. The Filter simulation was done in Matlab® environment. A standard Bit loading algorithm is utilized to compute the bits per tone over the ADSL frequency band. A plot of datarate for different techniques is presented. Results obtained with AWGN, 10 HDSL, 10 ADSL NEXT disturbers show a significant improvement in Rate reach performance upwards of 2 Mbps
