23. COEFFICIENT TAP LEAKAGE FOR FRACTIONALLY-SPACED EQUALIZERS Abstract of the Disclosure A quadrature amplitude modulated (QAM) data signal transmitted at T symbols per second is sampled in a data receiver at a rate of 2/T samples per second and applied to a transversal-type equalizer structure having taps spaced at T/2 second intervals. A demodulated equalized signal generated once every T seconds, is quantized to form a decision as to the value of the original modulating data symbol. An error signal is formed in response to the pre- and post-quantized values of the demodulated equalized signal. Tap coefficients used in generating the equalized signals are updated in response to a) a correction term which is a function of the error signal and b) a predetermined tap leakage term which has a constant magnitude. The introduction of the tap leakage term maintains the coefficient values at minimum levels.
