Abstract
A communication device such as a mobile station (410) for a spread spectrum communication system includes a receiver (100) having an adaptive equalizer (104) which suppresses interference on a received spread spectrum signal to produce an equalized signal (126). A pilot channel demodulator (110) demodulates the equalized signal to produce an estimate of the pilot channel (140). A summer (112) compares the pilot channel estimate and a predetermined data pattern to produce an error signal (124). A traffic channel demodulator (108) demodulates the equalized signal to produce one or more traffic channels.
