摘　　要：针对无线多用户多投影系统信息传输存在安全隐患的缺点,在研究无线投影软、硬件及网关接收协议基础上,设计了一个多用户多投影展示体系,并提出利用基于噪声聚合的安全增强编码方法对接收器与发送器传输信号进行编码,从而实现可靠、安全的通信过程。仿真分析结果表明,本方法能够有效抑制窃听者信号,极大提高了信息传输可靠性及安全性。In order to solve the security problem of information transmission in wireless multi-user multi projection system,a multi-user multi projection display system is designed based on the research of wireless projection software,hardware and gateway receiving protocol,and a security enhanced coding method based on noise aggregation is proposed to encode the transmission signals of receiver and transmitter,so as to realize reliable and safe communication.The simulation results show that the proposed method can effectively suppress the eavesdropper signal and greatly improve the reliability and security of information transmission.
