Hello, I take an interest in DSP only from a few weeks and I intend to processing a return signal from a radar with a TI starter kit utilizing Matlab simulink. The DSP must generate a sawtooth signal with a certain period and the signal processing (filter, FFT, etc..) of the synthetized return radar signal must begin when begin the sawtooth. It is rigth utilize a triggered subsystem both for gene...

## EbNo vs BER in Simulink

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...

## switch(decision?) block in simulink

I want to add a swith to my simulink simulation blocks. Output blockA is fed to blockB, and that from blockB is fed to blockC. blockA -> blockB -> blockC I want to revise it like: if(output from blockA is zero) then blockA -> blockC //bypass blockB else blockA -> blockB -> blockC end if Can anyone tell me which block to use? I fund SwitchCase block but that needs specific valu

## Real Time Workship Video Capture Code for CCS

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...
