Concatenated Orthogonal / Pn Codes for Ds-cdma Systems in a Multi-user and Multipath Fading Environment1
نویسندگان
چکیده
The crosscorrelation and autocorrelation properties of the concatenated orthogonal/long PN sequence are analyzed. The results are used to evaluate the performance of this new spreading scheme for direct sequence spread spectrum CDMA in a multiuser/multipath fading environment. The channel is assumed to be Rayleigh or Rician faded. The analysis is carried out using two types of receiver: single correlation receiver and maximum ratio combiner.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملLong codes for generalized FH-OFDMA through unknown multipath channels
A Generalized Frequency Hopping (GFH) OFDMA system is developed in this paper as a structured long code DS-CDMA system in order to bridge frequency hopped multi-carrier transmissions with long code DS-CDMA. Through judicious code design, multiuser interference is eliminated deterministically in the presence of unknown frequency-selective multipath channels. Thanks to frequency hopping, no singl...
متن کاملPerformance of DS-CDMA Over Measured Indoor Radio Channels Using Random Orthogonal Codes
Direct sequence spread spectrum, with its inherent resistance to multipath interference, has become a commercial reality for indoor wireless communications and has been proposed for personal communication networks. To allow multiple users within the limited bandwidths allocated by the FCC, codedivision multiple-access (CDMA) is needed. This paper analyzes the performance of CDMA systems using r...

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 ...

In this paper, we present different linear and nonlinear iterative data detection schemes for the asynchronous direct-sequence code-division multiple access (DS-CDMA) systems employing orthogonal signalling formats and long scrambling codes. Compared to the conventional receiver and other noncoherent multiuser detectors, coherent multiuser detection schemes achieve much better performance provi...
