A Hybrid Multi-Domain Index Modulation for Covert Communication
نویسندگان
چکیده
In this letter, a hybrid multi-domain index modulation scheme based on spreading codes domain and beam is proposed. our design, the information bit stream divided into two parts: one for covert transmission using of code other directional to improve error ratio (BER) performance in desired direction prevent eavesdropping. Then, joint boundaries statistical theory, average probabilities legitimate users eavesdroppers are derived. Moreover, we analyze BER validate through simulation results that proposed capable achieving better compared conventional coded wireless communication systems.
