Abstract

A near-end crosstalk (NEXT) canceller using a flne-grain pipelined architecture is presented. Performance of the proposed pipelined NEXT canceller is demonstrated in the 125 Mb/s twisted-pair distributed data interface and 155.52 Mb/s asynchronous transfer mode local area network applications. In addition, we analyze the computational complexity of the proposed pipelined NEXT canceller. It is shown that this architecture can be clocked at a rate that is 107 times faster than the serial architecture with a maximum loss of 2.0 dB in signal-to-noise ratio (SNR).
