Abstract
An adaptive apparatus and method for detecting a receiving signal employing constrained minimum mean square error (MMSE) criterion as an adaptive algorithm for detecting CDMA receiving signal. The apparatus comprises an adaptive filtering means; a channel estimating means; a signal restoring means; a selecting means; a reference signal generating means; an error calculating means; and a tap weight controlling means. In the apparatus, an adaptive filter can be normally operated even if compensating a phase and amplitude of a channel at the same time.
