BPSK modulation and Raised Cosine Filtering

I have problem with this code:

data = randi([0 1],40,1);
bpskModulator = comm.BPSKModulator;
bpskModulator.PhaseOffset = pi/4;
modData = bpskModulator(data);
scatterplot(modData)
modData = step(bpskModulator, data);

throwing error "Unable to resolve the name comm.BPSKModulator."

any help please?

add "coder.extrinsic('comm.BPSKModulator')"

Hi Martin,

From what I have understood, your issue seems to be the presence of the following error: “Unable to resolve the name comm.BPSKModulator”. The issue you are facing is usually caused by a path error, where the object is unable to access the correct path. Run the following commands in MATLAB in the following order

restoredefaultpath
savepath

After executing these commands, restart MATLAB.

I hope your issue gets resolved.

Thanks
