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...

PN Code Acquisition Using Smart Antenna and Adaptive Thresholding CFAR Based on Ordered Data Variability for CDMA Communications

Recently, a novel approach for PN code acquisition of direct sequence code division multipleaccess (DS-CDMA) systems in Rayleigh fading multipath channel was proposed in [1]. The authors considered a combination of adaptive thresholding constant false alarm rate (CFAR) and smart antennas to increase the system capacity and consequently enhance the detection performance. This paper considers sti...

Acquisition for DS/CDMA systems with multiple antennas in frequency-selective fading channels

This work was supported by the Brain Korea 21 Project. Abstract~A code acquisition scheme is proposed for DS/ CDMA systems with multiple antennas. The proposed scheme employs a new search scheme, referred to as sparse search, to utilize multipath signals in reducing mean acquisition time over frequency-selective fading channels. The mean acquisition time performance of the proposed scheme is an...

Serial acquisition of DS-CDMA signals in multipath fading mobile channels

This paper compares the mean acquisition time (MAT) performance of two serial search acquisition schemes over frequency-selective multipath Rayleigh fading channels. Both the conventional cell-by-cell detection and the novel joint two-cell detection are characterized. In contrast to the majority of published results considering only one correct timing state ( 1 cell) in the uncertainty region o...

Serial Acquisition Techniques for Ds-cdma Signals in Frequency-selective Multi-user Mobile Channels

This paper compares the mean acquisition time performance of two serial search acquisition schemes over frequency-selective multipath Rayleigh fading channels. Both the conventional cell-by-cell detection and the novel joint twin-cell detection are characterised. In contrast to the majority of published results considering only one correct timing state (H1 cell) in the uncertainty region of the...
