Blind Adaptive Single-user Receivers for Ds-cdma Systems in Frequency-selective Fading Channels

چکیده
| Linear minimum mean squared error (LMMSE) criterion can be used to obtain near-far resistant single-user receivers in direct-sequence code-division multiple-access (DS-CDMA) systems. A mod-iied version of the receiver, called LMMSE-RAKE receiver , has previously shown promising performance in frequency-selective fading channels. In this paper, both the convergence and BER performance of an adaptive LMMSE-RAKE receiver is compared to several other known blind adaptive single-user receivers. The results show that the proposed blind adaptive receiver can be used to improve the convergence and BER performance in comparison to other known blind adaptive receivers.

LMMSE Receivers for DS-CDMA Systems in Frequency-Selective Fading Channels
| The linear minimum mean squared error (LMMSE) criterion can be used to obtain near-far resistant single-user receivers in direct-sequence code-division multiple-access (DS-CDMA) systems. The standard version (postcombining) of the LMMSE receiver minimizes the mean squared error (MSE) between the lter output and the actual transmitted data sequence. Since the detector depends on the channel co...
متن کاملAn improved blind adaptive MMSE receiver for fast fading DS-CDMA channels
Blind adaptive minimum mean-squared errors (MMSE) receivers for multiuser direct-sequence code-division multiple access (DS-CDMA) systems that assume knowledge of the steering vector, i.e., the cross-correlation between the desired output and the input signal, are known for their robustness against channel fading as they do not attempt to explicitly track the channel of the user of interest. Ho...

Linear minimum mean squared error (LMMSE) criterion can be used to obtain near-far resistant receivers in direct-sequence code-division multiple-access (DS-CDMA) systems. The standard version of the LMMSE detector depends on the channel coeecients of all users and cannot be used in frequency-selective fading channels due to fast changes of channel phases which demands for continuous detector up...
متن کاملBit 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 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 ...
