Thank you Jeff.. Are these filters in software? Or fpga? Is there any function that we play with to get aliasing? i.e. how to disable such filters? Thank you Wahhab The B2XX bandwidth can be adjusted, but that is in addition to other filters designed to remove aliases based on the sample rat

Unicast/multicast/broadcast are networking terms for different types of addresses in a packet, and are relevant at Layer 2 and above. GNU Radio is (mostly) concerned with Layer 1 (the radio), where "broadcast" is an RF term. There is no "multicast" or "unicast" at this level. You can carry a

Hi Wahhab, As Kyeong had already pointed out, in this configuration, the bw limiting factor is the daughtercard. For the SBX the bandwidth is 40 MHz. There are other Ettus products covering the same frequency range which have wider bandwidth (80,120,160 MHz) but they seem to on

Dear Kyeong, Thank you for the reply. How about using USRP B210, do you think we can get aliasing by setting the RF bw=50MHz and sample at 2MHz? Thank you. Wahhab On Dec 29, 2017 12:19 AM, "Kyeong Su Shin" wrote: > Hello Wahhab, > > If I recall correctly, you can *not* change the bandwidth of S

Hi Weihan - When you simulate "over the air" inside GNU Radio, there are fewer wireless issues encountered & the data is much more likely to be received. Actual OTA is somewhat more challenging, especially if you're sending just 1 frame. Some suggestions, based on personal experience: * try se
