Adaptive LMMSE-RAKE Receiver for DS-CDMA Systems
نویسندگان
چکیده
Conventional RAKE receiver is near-far limited. 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. Depending on the optimization criterion diierent adaptive receivers are obtained. In this paper, a novel adaptive LMMSE-RAKE receiver is presented, which combines conventional RAKE and single-user LMMSE receivers. Depending on a quality indicator the receiver switches itself to diierent modes depending on the radio channel conditions.

|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 receiver minimizes the mean squared error between the lter output and the true transmitted data sequence. Since the detector depends on the channel coef-cients of all users, it cannot be impl...

This thesis studies the design and implementation of a linear minimum mean-square error (LMMSE) receiver in asynchronous bandlimited direct-sequence code-division multiple-access (DS-CDMA) systems that employ long-code pseudo-noise (PN) sequences and operate in multipath environments. The receiver is shown to be capable of multiple-access interference (MAI) suppression and multipath diversity c...

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 ...
