Covariance Analysis of a vector tracking GPS receiver based on MMSE multiuser Detection
In high dynamic conditions, using vector tracking loops instead of scalar tracking loops in GPS receivers is proved as an efficient method to compensate the performance. The Minimum Mean Squared Error detector as a multiuser detector is applied in the vector tracking loop for more reliability and efficiency. The Kalman filter does the two tasks of tracking and extracting the navigation data aft...
متن کاملRobust multiuser detection in impulsive channels based on M-estimation using a new penalty function
Introduction: Detection and estimation theory is one of the core investigation areas in communications. Multiuser detection (MUD) is an estimation problem in which different users transmit their signals through the same channel in a multiple access channel (MAC). In this way the receiver explores desired signal through the ambient noise and interference generated by other user signals. Multiuse...
متن کاملNonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...

متن کاملMultiuser Detection of Cdma by Iterated Soft{cancellation (turbo Multiuser Detection) Camera-ready Copy for Multiuser Detection of Cdma by Iterated Soft{cancellation (turbo Multiuser Detection)
Multiuser detection by iterated soft{decision interference cancellation is known to achieve almost single user performance in low and moderate interference scenarios. In this paper, it is shown how this detection scheme can be further improved by adaptive calculation of the soft{decision rule. This enables a signiicantly higher number of active users signaling within the same bandwidth to be de...
