TL;DR: Numerical and simulation results indicate that for realistic AWGN DS-CDMA systems with reasonably low signature cross-correlations the linear minimum BER filter and the MMSE filter exhibit approximately the same performance.

TL;DR: This work considers the problem of robust detection of a spread-spectrum (SS) signal in the presence of unknown correlated SS interference and additive non-Gaussian noise and derives the optimum decision fusion filter for receivers that utilize hard-limiting chip nonlinearities.

TL;DR: Two computationally efficient combined synchronization/demodulation schemes are proposed, developed, and analyzed based on the principles of minimum-variance distortionless-response processing and auxiliary-vector filtering, which exhibits enhanced performance in short data-record scenarios.

TL;DR: A DS-CDMA receiver is proposed that utilizes a simple pilot-assisted algorithm that estimates and then subtracts the desired signal component from the received signal prior to filter estimation and two recursive algorithms for the on-line estimation of the AV and MMSE/MVDR filter are developed and studied.

TL;DR: In this paper, the performance of blind adaptive linear self-synchronized receivers for asynchronous direct-sequence code-division multiple-access communications under finite data record adaptation is investigated, leading to analytical expressions that approximate the probability of coarse synchronization error of matched-filter-type and minimum-variance distortionless-response-type receivers.
