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