Abstract :
The unit-norm constraint optimization for joint shortening of channel and echo impulse response is presented in this paper. The optimization is performed in the mean square sense (MSE) and compared to unit-tap constraint joint shortening optimization. The proposed method could serve in performing joint echo cancellation and equalization for data transmission over category cables for the next IEEE standard on shortrange ultra high-speed copper interconnections used in data servers, high-performance computing centers, local area networks, etc. The main objective of the presented algorithm is to extensively reduce the power and implementation complexities of a 40GBASE-T system.
