Good day everyone,
My sincere apology in advance if this question has been asked before,
but i tried search thru the archives but to no avail.
Currently, I am trying to calculate the BER for GMSK, But first I
started off on a perfect channel without USRP.
My current block diagram is as follows:
“Random Source”
0s and 1s, 10^6 windows -> “Throttle” -> “GMSK Mod (default settings)”
-> “GMSK Demod (default settings)” -> “Error Rate Block”
I am feeding in “Error Rate block” with the random source and the “GMSK
Demod” Output.
I am getting BER of 50%… Anyone knows what is wrong?
In fact, I saved the input and output as binary files. I found out that
they are not very identical especially in terms of binary length. I
tried input 9 bits of binary and I obtained 63 bits from the GMSK Demod
Output.
Is there something that is missing?
Hope someone can advise me. Thank you
Best Regards,Sun
