Real-time FPGA-based Non-Cryptography System for Wireless Network
Traditional privacy techniques for wireless communications are facing great challenges, due to the open radio propagation environment and limited options of transmission techniques. A new bilateral pilot aided protocol is presented, with single-tone based burst transmission over slow time varying flat fading wireless channels, and is investigated to enhance the security of quadrature amplitude modulation (QAM) system. In this paper, a real-time and link privacy method with FPGA-based design is proposed, which is based on the characteristics of radio channel including randomness and privacy. For the proposed approach, the unique instant channel state information (CSI) of channel can be estimated in real-time by a proposed FPGA-based circuit to be used in giving confidentiality for transmitted data. The proposed approach is adequate for most real-time wireless communication systems.
