用于将RGB彩色图转化为灰度图的matlab代码！(Gray color map of the matlab code!)

This m file analyzes a coherent binary phase shift keyed(BPSK) and a amplitude shift keyed(ASK) communication system. The receiver uses a correlator(mixer-integrator[LPF]) configuration with BER measurements comparing measured and theoretical results. The bandpass and low pass used in the receiver are constructed using z transforms. (This m file analyzes a coherent binary phas e shift keyed (BPSK) and a amplitude shift keyed (ASK) communication system. The receiver uses a correlator (mixer-integrator [LPF]) config Education and other BER measurements comparing with measu red and theoretical results. The bandpass and l ow pass used in the receiver are constructed usi Vi z transforms.)
