Computes the minimum distance between two different shape polygons. (Vertex-vertex case)

最小方差无失真响应，波束形成，增强信号。(Minimum Variance Distortionless Response ,Digital Beamforming,Siginal Enhancement)

无线传感器网络QoS路由REER算法，matlab程序(QoS routing REER algorithm for wireless sensor networks )

it is a code in MATLAB for calculation of bit error ratio vs signal to noise ratio , for multiuser code division multiple access .. usually in any communication system calculation of BER is very important to know the performance of system .. so in this program multiuser CDMA system is used ,, spreading is done using HADAMARD matrix .. or WALSH code .. and BER vs SIGNAL to NOISE ratio graph is computed
