its job. Is there a
better way to implement similar algorithms, which occur frequently in
communication systems?
You'd need to buffer enough samples to get your delay. ie you don't care about
time as such, just think of it in samples :)

bits whereas ints are only 32.
I don't have a USRP yet, anyway.
Thanks!
Is a long 64 bits or do you have to use long long to get 64 bits?
Might I suggest that if you want a specific width data type you use
[u]int[8,16,32,64]_t?
It's portable too :)
