摘要：
A multi-user demodulator eliminating synchronization issues without interference cancelers. Threshold process is applied to the despread signal for extracting each user signal. The extracted signals are respread, and those respread signals other than a specific user signal are subtracted from the received signal to ideally extract the specific user signal.
