Blind Source Separation Enhanced Capacity-Expanded Anti-Jamming TT&C Communication Method

Aiming at the prominent problem that traditional spread spectrum TT&C systems cannot simultaneously achieve high information transmission rates and strong anti-jamming capabilities, this paper proposes a capacity-expanded antijamming TT&C communication method that organically combines an improved Parallel Combinatory Spread Spectrum (PCSS) waveform with Blind Source Separation (BSS) processing. At the transmitter, the system capacity is expanded through the combinatorial relationship of multiple pseudo-noise (PN) codes and the orthogonal transmission of I and Q branches. At the receiver, BSS processing is employed to enhance the system’s jamming tolerance without additional spectrum overhead. Simulation results demonstrate that the proposed method can expand the communication capacity of the TT&C system while guaranteeing its anti-jamming capability.
