Performance analysis of non-data aided SBIB receivers for CDMA systems
چکیده انگلیسی

In this paper, a non-data aided desired signal-blocked interference-blocked (SBIB) receiver with enhanced multiple access interference (MAI) suppression is proposed for direct-sequence code-division multiple access (DS-CDMA) systems over a multipath fading channel. Without using pre-known data, the proposed receiver can offer a similar performance as a non-blind maximum signal-to-interference-plus-noise ratio (MSINR) receiver, in which both the interference-plus-noise correlation matrix and the channel estimation are assumed to be correct. Performance analysis is carried out to examine the efficacy of the proposed receiver. Computer simulation results then confirm the correctness of the theoretical analysis and demonstrate that the proposed blind receiver can successfully resist MAI and outperform the conventional receivers.
