Multiuser detection for wireless communications systems in the presence of Interference

摘要

System and method for detecting transmissions from multiple users in a digital wireless communications system in the presence of interference. A preferred embodiment comprises derotating a received signal (510) by a specified amount, determining channel estimates (515), which can include the determination of the number of users (interferers plus a desired user), and extracting information (520) transmitted by the desired user from the received signal. Successive and parallel multiuser detection schemes are provided for extracting the information from the received signal.
