Regularized frequency domain equalization algorithm and its VLSI implementation

Approximation of Toeplitz matrices with circulant matrices is a well-known approach to reduce the computational complexity of linear equalizers. This paper presents a novel technique to compute linear equalizer coefficients in the frequency domain. It is shown how a regularization term can help to reduce the error caused by the frequency domain approximation. A corresponding VLSI implementation provides reference for the true silicon complexity and for the complexity increase associated with the proposed algorithm.
