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.

[ What is claimed is:] [1.] A communication device for receiving a spread spectrum signal which includes a pilot channel and traffic channels, the pilot channel substantially orthogonal to each of the traffic channels, the communication device comprising:an adaptive equalizer which adapts using the pilot channel, the adaptive equalizer receiving the spread spectrum signal and producing an equalized signal;a demodulator for demodulating the equalized signal to produce a demodulated traffic channel;a pilot channel demodulator which produces a pilot channel estimate; anda comparator for generating an error signal in response to the pilot channel estimate, the adaptive equalizer adapting in response to the error signal.
