Media-Based Modulation (MBM) is a novel transmission method whose main idea is embedding information in channel states. In this paper, new insights into the secure communication of MBM systems are presented. Using an information-theoretic framework, we first derive the expressions of the mutual information and the secrecy rate and find out the effect of antennas, channel realizations and other variables...
The classical preamble-based channel estimation for pulse shaping orthogonal frequency division multiplex/offset QAM (OFDM/OQAM) systems requires zero-value guard symbols to guarantee interference avoidance, which leads to low spectral efficiency. In this study, we cut down the preamble structure without zero-value guard symbol to reduce preamble resource overhead. However, the intrinsic imaginary...
