Blind Interference Suppression for Ds-cdma
نویسنده
چکیده
The use of a blind scheme for suppressing interference in direct-sequence code-division multiple-access (DS /CDMA) communication systems is investigated. In particular, we use a blind version of the partial-bit DS/CDMA receiver to successfully suppress narrow-band and nearfar multiple-access interference without requiring knowledge of other users’ spreading codes, timing or phase information. Performance results for a 23 user/100 chip BPSK DS/CDMA system indicate that the blind partial-bit DS /CDMA receiver using as little as 33 taps can suppress narrow-band and near-far multiple-access interference, either at the beginning of a transmission or during transmission as interferers gain access to the system.

Nonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...
متن کاملBlind Adaptive Successive Interference Cancellation for Multicarrier DS-CDMA
A new adaptive receiver design for the Multicarrier (MC) DS-CDMA is proposed employing successive interference cancellation (SIC) architecture. One of the main problems limiting the performance of SIC in MC DS-CDMA is the imperfect estimation of multiple access interference (MAI), and hence, the limited frequency diversity gain achieved in multipath fading channels. In this paper, we design a b...
متن کاملPerformance Comparisions of ICA Algorithms to DS-CDMA Detection
Commercial cellular networks, like the systems based on DS-CDMA, face many types of interferences such as multi-user interference inside each sector in a cell to interoperate interference. Independent Component Analysis (ICA) has been used as an advanced preprocessing tool for blind suppression of interfering signals in DS-CDMA communication systems. The role of ICA is to provide an interferenc...
متن کاملBlind Adaptive Interference Suppression for Direct-sequence Cdma
Direct Sequence (DS) Code Division Multiple Access (CDMA) is a promising technology for wireless environments with multiple simultaneous transmissions because of several features: asynchronous multiple access, robustness to frequency selective fading, and multipath combining. The capacity of DS-CDMA systems is interference-limited, and can therefore be increased by techniques that suppress inte...
متن کاملAdaptive step-size algorithms for blind interference suppression in DS/CDMA systems
This paper develops adaptive step-size blind LMS algorithms and adaptive forgetting factor blind RLS algorithms for code-aided suppression of multiple access interference (MAI) and narrowband interference (NBI) in DS/CDMA systems. These algorithms optimally adapt both the step size (forgetting factor) and the weight vector of the blind linear multiuser detector using the received measurements. ...
