TD-SCDMA, which is the "homemade" 3G standard in China, has received considerable attention and is believed to play a critical role in the development of China's mobile communication. Meanwhile, advanced MIMO and OFDM techniques shed light on the feasibility of high-performance 4G broadband systems. We discuss an evolutionary path of TD-SCDMA toward 4G systems in this article, which combines...
Code division multiplex access with cyclic prefix (CP-CDMA) is regarded as one of the best candidates for the broadband wireless communication systems in the uplink. This paper proposes a selective parallel interference cancellation (S-PIC) for uplink CP-CDMA. With less complexity and good resistance to near-far effect, the S-PIC can achieve better bit error rate (BER) performance than the conventional...
In this paper, a theoretical analysis of TDD-CDMA capacity constraint is presented firstly when employing the adaptive tracking and switched beam smart antenna techniques in both uplink and downlink. In uplink, the multi-user detection (MUD) technology is utilized and the smart antenna technique is involved, and the corresponding capacity and load evaluation is reinvestigated. Based on the proposed...
