I am trying to simulate a BPSK modulation scheme over an AWGN channel and compare the EbNo values with the generated BER in Simulink.The problem is that i need multiple values specifying Ebno in the AWGN channel blockset which i am unable to do so that i can compare them with the generated error rates. I am using a Bernouli Function generator as the input followed by BPSK modulation and AWGN chann...

Hello, I wanted to understand how RTW(Matlab) generates code for video capture for image processing on the dsp. The 'From Video Device' block in Simulink is not supported by RTW. So I just wanted to know what it is that RTW does when generating C code for CCS? Does this block have to be removed and RTW generates something automatically or is there another Simulink block that we have to put in...
