Abstract: In a CDMA communication system (100) capable of communicating between a receiver (20) and a transmitter (10) direct sequence spread spectrum communication signals (30), a system and method for synchronizing receiver bit timing and transmitter timing. Transmitter (10) transmits a training bit sequence (31) followed by a transmitter bit timing sequence (33). The receiver (20) adaptively determines a representation of a despreading chip sequence using a tapped delay line equalizer (400). Receiver bit timing offset is determined based on the representation of the despreading chip sequence and the transmitter bit timing sequence (33).
