This paper considers the link-level and network-level performance of code division multiple access (CDMA) pilot interference cancellation (pilot IC) technology, a low-complexity advanced receiver technology being considered for use in commercial third generation (3G) CDMA cellular systems. The concept behind this technology is to estimate and cance...

Pilot interference cancellation (IC) has recently received consideration for use in third generation (3G) CDMA cellular receivers. In this paper, we derive an expression for evaluating the bit error rate (BER) performance of both the RAKE and pilot IC receivers, under conventional random spreading code assumptions. The approach can provide results...

Pilot interference cancellation (IC) in mobile receivers has recently gained attention for CDMA cellular networks. In this paper we address the accuracy of the pilot interference cancellation at the receiver. In doing so, we consider the effects of channel estimation, timing estimation, receiver tap-spacing granularity, and the other receiver imper...

Common pilot cancellation in mobile receivers has recently gained attention for CDMA cellular networks. This paper presents system simulation results showing that the network capacity gains achievable from both ideal and hardware resource limited pilot cancellation receivers are significant. We show that the highest gains are achievable from both i...

We present novel approaches to reverse link signal reception in IS-95 CDMA systems that utilize space time adaptive processing (STAP), multi-user detection (MUD), and combined STAP/MUD techniques to implement receivers that are resistant to the near-far problem. We also present experimental results that were obtained by applying STAP, MUD, and comb...

Direct-sequence code-division multiple access (DS-CDMA) is a popular wireless technology. In DS-CDMA communications, all of the users' signals overlap in time and frequency and cause mutual interference. The conventional DS-CDMA detector follows a single-user detection strategy in which each user is detected separately without regard for the other...

A new family of multistage low-complexity linear receivers for direct sequence code division multiple access (DS-CDMA) communications is introduced. The objective of the proposed design is to mitigate the effect of multiple access interference (MAI), the most significant limiting factor of user capacity in the conventional DS-CDMA channel. The rece...
