An adaptive receiver apparatus comprises demodulating means for demodulating a reception signal, adaptive equalization means for equalizing a demodulated output to output an equalized signal, an difference signal upon equalization and a channel impulse response estimate estimated upon equalization, noise level detecting means for detecting a noise level based on the difference signal upon equalization, channel impulse response variation magnitude detecting means for detecting a variation magnitude of the channel impulse response estimate at a predetermined interval, and coefficient control means for adjusting a coefficient determining a tracking property of an adaptive algorithm of the adaptive equalization means depending upon the variation magnitude of the channel impulse response estimate detected by the channel impulse response variation magnitude detecting means and the noise level detected by the noise level detecting means.
