An iALM-ICA-Based Antijamming DS-CDMA Receiver for LMS Systems

We consider a land mobile satellite communication system using spread spectrum techniques where the uplink is exposed to multitone jamming attacks, and the downlink is corrupted by multipath fading channels. We propose an antijamming receiver, which exploits inherent low-dimensionality of the received signal model, by formulating a robust principal component analysis-based recovery problem. Simulation results verify that the proposed receiver outperforms the conventional receiver for a reasonable rank of the jamming signal.
