In view of the positioning, orientation and attitude measurement for large special vehicles, how to accurately receive vehicle running status, monitor all aspects of transportation, and to provide decision-making information for drivers and managers has become a key problem. This research puts forward to install three GPS receiving terminal antenna on the same baseline, while the distance between...
This paper presents three low-complexity, yet effective, multiuser detectors (MUDs) for the uplink of spatial-frequency-time-domain (SFT-domain) spread multicarrier (MC) direct-sequence code-division multiple-access (DS-CDMA) systems. Each MUD first converts a received signal into the corresponding format. It then detects the transmitted symbols iteratively by using a one-domain (1D) minimum-mean-square-error...
This paper presents three multiuser detectors (MUDs) for the uplinks of spatial-frequency-time-domain (SFT-domain) spread multi-carrier (MC) direct sequence code division multiple access (DS-CDMA) systems. First, aiming at achieving significant performance gain, we propose a joint optimum SFT-domain MUD based on minimum mean square error (MMSE) decision rules. Further, to reduce the computational...
This paper presents an iterative, yet effective minimum mean square error (MMSE) space-time multiuser detector (MUD) with the assistance of soft interference to enhance the performance in the multipath code division multiple access (CDMA) systems. The proposed space-time MUD is of rank one and comprises of a spatial filter and a temporal filter. To offset the performance loss due to such a constraint,...
This paper proposes a simple, yet effective generalized sidelobe canceller (GSC)-based Capon multiuser receiver for the Alamouti space-time block coded (STBC) multiple-input multiple-output code-division multiple-access (MIMO CDMA) systems. The new receiver makes full use of the space diversity provided by the antenna array and the time diversity provided by the decision feedback (DF) from the outputs...
This paper presents an effective multi-rate multiuser detector (MUD) for the uplink of single-input multiple- output (SIMO) multi-carrier code division multiple access (MC- CDMA) systems. The MUD considered is an iterative receiver which utilizes the soft information to refine the estimation of the interference to enhance the interference cancellation capability. More specifically, users with different...
