HI

i am using simulink for my work, i have a a digital BPSK modulator which takes binary data and then modulates it, now i want to see the analog output of it in simulink

ie i want to see the signals changing phase in analog form, and also in this way i can see how the AWGN can affect my signal

so input is binary
BPSK modulator

but i want to see the analog singal which travels in the channel in simulink

ne ideas !

From what i have tried out, this awgn block in simulink is a discrete one. i mean it takes sampled values as input, not the continuous (Sample time=0).

So i was wondering whether u try modelling the channel as a transfer function, and then adding white noise using a Gaussian Noise generator?
