Cost-effective echo and NEXT canceller designs for 10GBASE-T ethernet system

—In this paper, new echo and NEXT cancellers are proposed for echo and NEXT cancellation in full-duplex digital transmission over 10GBASE-T system. The proposed cancellation schemes inherit the concept of the adaptive interpolated FIR (AIFIR)-based crosstalk canceller, where the long portion is modeled by an adaptive sparse FIR filter. Furthermore, we also employ the channel shortening technique to shorten the impulse response of crosstalk interference. Hence, the complexity of echo and NEXT cancellers can be greatly reduced. Simulations show that compared with the conventional
