Re: [Discuss-gnuradio] Channel measurements?

That is not always true, actually it depends on when and where you are going to measure a channel, For example in a office during a day, channel could change several times in a second. So for indoor applications a channel sounder should be as fast as possible. I can refer you to these papers

[Discuss-gnuradio] new 802.11b receiver

Hi, As you may know, BBN guys have developed a receiver for 802.11b. But due to the USB limitation, they had to cut the spectrum which leads to low SNR. We have developed a new receiver by doing some operation (especially de-spreading) inside the FPGA (before sending data to USB). Therefore,
