Least-squares time-domain deconvolution for transversal-filter equalisers

The N tap weights for a transversal-filter equaliser are calculated efficiently by solving a Toeplitz set of linear equations which represents the discrete-time convolution of filter and system impulse responses. Computation time is proportional to N2, approximately. Discrete Fourier transforms are not used. For many practical designs, the procedure is suited to small, desk-top programmable calculators, since it requires only multiplications and additions of real numbers and about 5N data storage registers.
