[Discuss-gnuradio] How to estimate SNR in ofdm benchmark example?

2013-09-06 Thread Yingjie Chen
Hi guy, Thanks in advance. I am currently doing a project in ofdm benchmark example. If I want to estimate the SNR in receiver side using USRP2, dose anyone know which block should I use and how should I connect it? Appreciate your great help. Best, Kay

Ruoyu, Buying a commercial Iridium antenna is, I'm sure, an ideal solution for your work. If the antenna is entirely passive (i.e it has no LNA and filter built in) then it will still pick up frequencies outside the band of interest. And, though attenuation will increase as these environmental

Dear Josh, Thanks for your reply. I move the code get_tags_in_range in digital_correlate_access_code, so it will be executed when digital_correlate_access_code runs. I start the sender first and then the receiver. But I still get no tag. Does the beginning of stream mean the point just the
