Could be the same thing I'm messing with now: cycle slip. If your data clock recovery misses a bit, then the two streams you're comparing are no longer in sync, meaning your result will be essentially random. You can verify this by saving both streams and comparing them.All the bestLaur2015-05-20 22:09 GMT+03:00 Damon <address@hidden>:_______________________________________________Hi everyone,
I am testing the BER performance of the gmsk of GNURaido with two USRP, one as a transmitter, and another as a receiver.
I find that the error bits would cause the subsequent bits getting error.
The received bits are compared with the transmitted bits, and if one bit is received correctly, a '0' is marked at the position, otherwise a '1' marked.
In the following test result, the front part of bits are received correctly. But I get lots of error bits after some bit which is not received correctly.
How to explain this?
