Dear SangHyuk, please be aware that digital receivers aren't really easy to make more CPU efficient; a real-world receiver not only has to convert received symbols to bits, but has to do the frequency and frame synchronization as well as a timing recovery; high-bandwidth transceivers must go

Dear Marcus, I'm always appreciated your help. I did ./benchmark_rate --rx_rate 25e6 and it worked well. Then, I should make it simple. Very thanks you! 2016-04-07 18:49 GMT+09:00 Marcus Müller : > Dear SangHyuk, > > On 07.04.2016 08:25, SangHyuk Kim wrote: > > Hi

Hi all, I'm trying to solve Rx overflow problem. I am using USRP N210 and CBX daughter board. As I know, my machine's maximum sample rate is up to 25 MSps. Yes, it works well at Tx (ex ./benchmark -f 2.5G -r 2500). However, when I use USRP to Rx mode (ex ./benchmark -f 2.5G -r 2500),
