抄録(英) In this paper, we propose a new interference cancellation technique of DS-CDMA for improving communication quality and increasing the number of simultaneous communication users for satellite communications. The DS-CDMA transmitter multiplies each user's signal by a distinct code. The detector receives a signal composed of the sum of all user's signals, which overlap in time and frequency. In a conventional DS-CDMA system, a user's signal is detected by correlating the entire received signal with that user's code. However, multiple access interference (MAI) is a factor which limits the capacity and performance of the DS-CDMA system. Therefore, this paper proposes a new interference cancellation technique for DS-CDMA based on discovery of spreading codes of interference signals and maximum correlation detection.
