Abstract
A multi-user demodulator eliminates synchronization problems without interference cancellation. A threshold process is applied to a despread signal to extract each user's signal. The extracted signals are respread, and those respread signals other than a specifier user's signal are subtracted from the received signal to ideally extract the specific user's signal.
