چکیده
Abstract We propose an extended one-shot decorrelating detector (EOS-DD) for asynchronous DS/CDMA systems in frequency selective fading environments. The EOS-DD extends a processing window to several symbol duration. The received signal over an extended window is utilized for the decorrelator in the EOS-DD. The effects of the window size on BER performance are investigated by numerical analysis. Analysis and simulation show that the EOS-DD is superior to the one-shot decorrelating detector (OS-DD) and finite memory length truncated decorrelating detector (FIR-DD) in terms of noise enhancement and near-far resistance.

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...

In this work, we propose an MMSE multiuser detector for asynchronous DS/CDMA systems operating over frequency-selective fading channels. It is shown that computation of a conditional MMSE estimate of the bit to be decoded may be carried out with a computational burden linear in the processing gain N . We also give a closed-form formula for the Error Probability and the Nearfar Resistance of the...

In order to reduce the computational complexity of the decorrelating detector in multipath fading asynchronous CDMA channels, we consider implementing it by linear multistage successive interference cancellation (MSIC), derived from the Gauss-Seidel iterations. In this paper we propose a multipath decorrelating SIC (MD-SIC) with differentially coherent equal gain combining (DEGC). The convergen...

This paper presents a technique for blind multiuser detection in asynchronous direct sequence-code division multiple access (DS-CDMA) systems over Nakagami-m fading channels with impulsive noise.

متن کاملOn the performance of O3BPSK LDD with diversity combining techniques over fading channels
Zheng and Barton developed a convenient signaling scheme (orthogonal on-off BPSK (OBPSK)) with a simple one-shot linear decorrelating detector (LDD) for near–far resistant detection in asynchronous DS/CDMA systems. This paper studies the performance of the OBPSK LDD system over a frequency-nonselective and slowly fading channel. Three types of channel model are considered, namely Rayleigh fadin...
