Hi, I'm trying to model a partial band jammer in simulink. For that i have used a Band stop filter (IIR elliptic), as a channel to attenuate the signal for the frequency band being jammed. Now i'm trying to plot the BER vs Eb/No curve using BERTOOL, but i'm facing a problem regarding the calculation of Eb/No. Basically i wud like to calculate the Eb/No of a band stop filter (being used...

I have some questions regarding implementing OFDM in Simulink... I'm using BPSK, thus my output after BPSK would be a complex number. I've splited up the real (16 samples) and imag (16 samples) numbers into 2 matrices. I plan to use IFFT with 64 samples. Except for the DC (sample 1), Nyquist center frequency (sample 32) and the real (13~31) and i

Hi guys, I'm working on a project with fixed-point toolbox on Matlab. I need to seriously sum tons of fixed point objects, and found there's no vectorized method around to do so. Just found that "Matrix Sum" in Simulink might do what I need, but I'm quite not sure how to call those blocks from .m code. I traced that, and found that sdspmsumprod.mexw32 seems to do the magic, but there's ...
