چکیده
In this paper iterative blind estimation of the complex amplitudes of the users is considered. A Gaussian mixture model formulation of the problem is introduced and Expectation Maximization (EM) algorithm for estimation of parameters for Gaussian mixture observation model is used. Simulation results compare the performance of the proposed algorithm with the Cramer-Rao bound.

In this paper, we focus our attention on blind demodulation for DS-CDMA transmission in the context of radio surveillance and military applications. We present a blind demodulation technique for DS-CDMA transmission over frequency selective channels. The technique exploits the autocorrelation properties of the transmitted signal to estimate the parameters (symbol duration, timing offset, phase ...

The oblique projection supports the framework to resolve a signal space into desired signal and interference subspaces. This paper presents subspace-based detection methods using the oblique projection for the CDMA channel. For the synchronous case, it is shown that this detector represents the geometrical form of the decorrelating detector, and performs a complete rejection of interfering sign...
