The spread spectrum technique is widely used and effective in combating narrowband interference with a moderate power as well as co-channel interference (CCI) and noise. However, it requires a configuration with long signature sequence for interference suppression, which is practically impossible. In addition, a system will exhibit a substantial degradation in performance due to both strong interference and desired coherent signals introduced by multipaths. In this paper, a novel detector is first proposed to determine the number of strong interferers for direct sequence spread spectrum (DSSS) based communication systems. Furthermore, the blind interference-blocked (IB) maximum signal-to-noise ratio (MSNR) beamforming is then proposed to collect desired coherent signals and to suppress strong interference. Theoretical analysis and numerical results demonstrate that the proposed IB-MSNR beamformer can achieve nearly the same performance as the optimal non-blind beamformer.
