物理层网络编码，也称为双向协同通信，采用的是BPSK加差分调制，主要分析系统的BER曲线(Physical layer network coding, also known as two-way collaborative communication, using BPSK differential modulation increases, the BER curve of the main analysis system)

this code is regarding to one simple network area. this code consists of some access points and link between them using distance relation. some access points are far away the signal transmitted

here is the matlab files for image array processing
