Frequency based Rate Separation for Dual rate CDMA Signals
نویسندگان
چکیده
Recently there has been considerable research on develop ing receivers for multi rate synchronous DS CDMA systems The previously proposed receivers operate on the complete received signal without separating users of di erent rates Multi rate users occupy di erent bandwidths and this pa per explores user separation by exploiting these bandwidth di erences Receiver structures which use lters to achieve frequency based rate separation and then apply single rate detection schemes are considered for a dual rate synchronous CDMA system Such a scheme enables a tradeo between complexity and performance The probabilities of error for the proposed receivers are derived Comparisons are made between the proposed receivers and single rate matched lter and the decorrelating detectors

Blind Channel Estimation and Multiuser Detection for Multi-rate Cdma Communications
The future wireless communications systems should be able to offer wide variety of applications, which have vastly different quality of service (QoS) requirements. The time-variable QoS may require the support of variable bit rates on the wireless links to the individual users. Multi-rate DS/CDMA is a promising basis on which to support the variable bit rates on the individual wireless links. C...
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 In Dualrate DS-CDMA Systems Using ICA
This article proposes an ICA-based blind multiuser detection technique to detect the signal of the desired user in a dual rate DS-CDMA system. In the present competitive scenario, communication is the most important tool in business and it has become a necessity to remain connected. Depending on the nature of data and quality of service requirements, users transmit signals at different rates. D...
متن کاملJoint Closed-Loop Power Control and Base Station Assignment for DS-CDMA Receiver in Multipath Fading Channel with Adaptive Beamforming Method
In this paper, we propose smart step closed-loop power control (SSPC) algorithm and base station assignment based on minimizing the transmitter power (BSAMTP) technique in a direct sequence-code division multiple access (DS-CDMA) receiver in the presence of frequency-selective Rayleigh fading. This receiver consists of three stages. In the first stage, with conjugate gradient (CG) adaptive ...
متن کاملFrequency-Domain Pre-Equalization for MC-CDMA/TDD Uplink and Its Bit Error Rate Analysis
In multi-carrier code division multiple access (MCCDMA) uplink (mobile-to-base station), since different users’ signals go through different frequency-selective fading channels, large multi-access interference (MAI) is produced. The use of frequency-domain equalization reception can only partially restore the orthogonality among different users’ signals, resulting in a severe degradation in the...
