“…Although these blind MUD schemes are effective to suppress MAI in different situations, but the performance of these detectors will be severely degraded if there is hostile jamming in channel. Harmonic jamming, partial-band jamming and linear swept-frequency jamming are effective to jam CDMA communication systems [11,12]. The detectors discussed above do not take the hostile jamming into consideration but treat it as received noise, so their performance will be severely degraded in hostile jamming dominant scenario.…”

The authors investigate the problem of blind multi-user detection (MUD) for uplink of asynchronous direct-sequence codedivision multiple access (DS-CDMA) systems with hostile jamming. To cope with the lack of prior knowledge of spread signals, hostile jamming and channel state information, the authors propose a scheme based on blind source separation (BSS) to solve this problem. Dual receive antennas are used in the proposed scheme. By exploiting the structure of the two received signals, a BSS model with dependent sources is formed, and then blind hostile jamming cancellation and MUD are obtained by solving this BSS problem. The proposed scheme does not require to know any information about the hostile jamming, and can work well under multiple kinds of hostile jamming. Simulation results further demonstrate that if such proposed approach is used to cancel hostile jamming and make MUD, then the bit-error-rate performance can be substantially improved as compared with earlier detectors.
