Base_on_BP_neural_networ_PID_controller_and_MATLAB

This is a project in communication domain. It uses the greedy and RCA algorithm to improve the throughput. It uses window ofdm technique . In transmitter side i used IFFT and in receiver side FFT is used. It uses single user channel .

QUIVERS(x,y,u,v,Gscale,Spos,Sunit) plots velocity vectors as arrows with components (u,v) at the points (x,y). The matrices X,Y,U,V must all be the same size and contain corresponding position and velocity components (X and Y can also be vectors to specify a uniform grid).
