Envelope-constrained time-domain deconvolution for transversal-filter equalisers

A deconvolution algorithm is presented for calculating the N tap weights of a transversal-filter equaliser. The procedure attempts to control the size of individual, time-domain response errors rather than simply minimise total mean-square error of the response. A least-square error solution for the tap weights is iteratively modified, using only elementary algebraic matrix operations, in an effort to satisfy tolerance constraints on the envelope of the equalised impulse response. The algorithm is suitable for digital computation.
