The fast development of wireless communications has generated the demand for network systems. However, in order to meet these requirements, many different kinds of access systems have to be developed. As a result, this work offers a novel approach to evaluating CDMA’s effectiveness for Multi-user Detection (MUD) and interference cancellation. The receiver uses spatial signatures and user coding to identify users. This research investigates the accurate calculation of MUD interference for only one sector of the cell using a CDMA system that supports K simultaneous data senders. The Bit Error Rate (BER) estimates for each individual user can be obtained. Then, the Parallel Interference Canceller (PIC) has performed as a suboptimal multi-user predictor. A performance analysis of the proposed CDMA model without and with PIC receivers is evaluated. The results demonstrate that the proposed model is significantly improved, with FER of 8.5%, Gain of 1.8 dB, and Speed of 50 mph, in 5 users when compared to existing models, namely 2D-HSSZCC, MSSSR, and DPPIC, respectively.

摘要

The fast development of wireless communications has generated the demand for network systems. However, in order to meet these requirements, many different kinds of access systems have to be developed. As a result, this work offers a novel approach to evaluating CDMA’s effectiveness for Multi-user Detection (MUD) and interference cancellation. The receiver uses spatial signatures and user coding to identify users. This research investigates the accurate calculation of MUD interference for only one sector of the cell using a CDMA system that supports K simultaneous data senders. The Bit Error Rate (BER) estimates for each individual user can be obtained. Then, the Parallel Interference Canceller (PIC) has performed as a suboptimal multi-user predictor. A performance analysis of the proposed CDMA model without and with PIC receivers is evaluated. The results demonstrate that the proposed model is significantly improved, with FER of 8.5%, Gain of 1.8 dB, and Speed of 50 mph, in 5 users when compared to existing models, namely 2D-HSSZCC, MSSSR, and DPPIC, respectively.
