چکیده
In this paper, estimation and tracking of the propagation delays, also known as code acquisition and tracking, in an asynchronous DS-CDMA system are considered. Of special interest is the performance in a near-far environment and the proposed estimator is shown to be near-far resistant. The suggested technique is subspace based and relies on recursively tracking the signal subspace, followed by a subspace fitting algorithm. Numerical results shows that the algorithm is well suited for delay estimation in a near-far envi-

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...
متن کاملPropagation Delay Estimation of Fading Ds-cdma Signals
In this paper we consider the problem of estimating the propagation delays of the transmitted signals in an asynchronous direct-sequence code division multiple access (DS-CDMA) system operating over a fading channel. Two estimators based on subspace techniques are compared and the Cram er-Rao Bound, a lower bound on the variance of any unbiased estimator, is derived. Special attention is paid t...

In this paper we consider the problem of estimating the propagation delays and relative amplitudes of the transmitted signals as well as detecting the data bits in an asynchronous direct-sequence code division multiple access (DS-CDMA) system operating over a fading channel. A subspace based estimator is proposed for estimating the propagation delays. The path gains and data bits are estimated ...
متن کاملApplications of Maximum Likelihood Algorithm in Asynchronous DS-CDMA Systems
In this paper, we treat the problems of propagation delay and channel estimation as well as data detection of orthogonally modulated signals in asynchronous DS-CDMA system over fading channels using the maximum likelihood (ML) approach. The overwhelming computational complexity of the ML algorithm makes it unfeasible for implementation. The emphasis of this paper is to reduce its complexity by ...
