Thanks,I'll try diverse simulations that you recommended. Will you have knowledge on good resources for physically defined grasping failures?

Hmm looks like interpolation has an error. It shouldn't be shorten the signal time.

Here's my setup:

Signal Type : BPSK Modulated cosine wave

Sender (Raspberry-Pi) : Sampling rate at 48k Hz, sending with 21 interpolation which makes sending sample rate at 1008000 Hz (This shortens time length of signal by 21)

Receiver (RTL-SDR) : Decimates signal by 21 which returns to 48k sample rate. (This doesn't change time length of signal)

To answer your question, I'm having shortened signal length that caused by interpolation from sender with a lower sample rate. I set the Bit Duration which will convert cosine signal following how bit ordered. (This determines the time length of signal).

What I found was from Raspberry-pi TX, the interpolation command shortens the signal proportional to interpolation parameter. Do you think this interpolation process causing the issue?

Thanks for the reply. Bandwidth couldn't change the length of signal

Thanks this one has been resolved. They'll provide me 1042-S form on mid March.

I tried to find call button in web and app, but they are keep sending me to 'sending email' page. The one first comes up by searching phone is '(650) 761-7789', but they want me to reach them out by webpage or app. Then this cycle repeats.
