چکیده
In this paper, a vector channel madel is pposed and some statistical pmperties of the asymptotic efficiency of the decorrelating detector with base-station awys are investigated. It is shown that we can get gain over the conventional deamlator by employing antenna arrays and the gain i n " s as the number of antennas inneases and the angle dispersion It is also shown that we can increase the asymptotic efficiency of the decorrelating detector with base-station antenna amys up to unity if we use infinite number of antennas when the channel is angle-nondispexsive: we cannot, however, incn?ase the asymptotic efficiency of the decomlating detector by employing base-station antenna arrays if the dispersion is infinite.

Extended One-Shot Decorrelating Detector for Asynchronous DS/CDMA Systems in Multipath Fading Channels
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...

Abstract – A novel hybrid multiuser detection scheme that jointly uses linear and nonlinear interference suppression techniques is developed for high-speed direct-sequence code-division multiple-access (DS/CDMA) communications in multipath frequency-selective fading channels. The detector detects signals in a symbol-by-symbol style. Conventional decorrelating detectors suffer from the noise enh...
متن کاملThe adaptive path selective decorrelating detector: performance analysis with channel estimation errors
In this paper, the multipath decorrelating (MD) detector which is used in code division multiple access (CDMA) systems to eliminate multiple access interference (MAI) is considered. The MD detector requires the inversion of a signature sequence correlation matrix. This process is computationally expensive and it also enhances the channel noise. Recently, an adaptive path selective decorrelating...
