Abstract
A communication method in an adaptive CDMA communication system (100) capable of communicating a direct sequence spread spectrum communication signals which comprise bit sequences coded with spreading chip sequences. The method includes the steps of transmitting a DS-SS communication signal (30) having a training bit sequence (31) coded with spreading chip sequence. The method includes the step of despreading the DS-SS communication signal based on the training bit sequence (31) during a training interval. The DS-SS communication signals is despread by adaptively determining a despreading chip sequence. Then, following the training interval determining chip timing offset during a chip timing interval. Finally, bit timing offset is determined during a bit timing interval following the chip timing interval.
