| Summary: | A fast switching spatial modulation scheme is proposed to improve the secrecy performance of the spatial modulation signal. The signal is a space-spread-spectrum signal associated with the channel information because of fast antenna switch. In this way, the desired receiver can demodulate the received signal according to the agreed antenna switching sequence using the relevant receiving method. Without the switching sequence of the information, eavesdroppers cannot get any useful information from the received signal. Simulation results show that the signal hidden in the background noise has a better secrecy performance at physical layer than traditional spatial modulation signal. |
