In recent days, cooperative diversity and communication security become important research issues for wireless communications. In this paper, to achieve LPI (low probability of interception) and high throughput in the cooperative SC-FDMA (Single-Carrier Frequency Division Multiple Access) system, a new SFBC combined physical layer transmission scheme is proposed, where, a new SFBC combined encryption algorithm is applied, adaptive modulation based on CSI (channel state information) is further considered. By doing so, neither relay node nor eavesdropper intercepts the information signals transmitted from UT (user terminal). Simulation results show above new SFBC combined physical layer transmission scheme can bring in higher transmission safety and secrecy rate, further derive better transmission performance and transmission throughput.
