Re: [Discuss-gnuradio] Measure BER

[irene159]

Hi! 

I’ve started performing modulation and demodulation on the same machine but
the main purpose is to make them work separately afterwards. 
I’ve seen some BER values on the forums and I was wondering if an “official”
block had already been developed to measure it. 

1) Tom, May I please have a look at your block calculating BER?

2) When comparing data sent and data received, how can we detect bit lost in
order to avoid clock shifting? In other words, if I’m sending “11010110” for
example, and that the 4th bit is lost, a simple comparison will compare tx :
“11010110” with rx : “1100110”. Detecting a lost is easy because the number
of bits in reception will be inferior to the number of bits sent, but how
can continue to compare the rest correctly?
