Hi Jacqueline, judging from the file name (_1Msps), the sampling rate is 1 MS/s. When it comes to signal bandwidth – a complex 1MS/s stream can contain /up to/ 1 MHz of bandwidth, but FM broadcast radio stations typically use something like 75 kHz of bandwidth for their FM signal. Best regards,

Hello Cristian: I am not too familiar with cmake and gr-802-11, but you probably have to modify cmake files and run cmake again if the files do not automatically get added. I suggest try editing CMakeLists.txt (the one located in lib directory). Regards, Kyeong Su Shin On Thu, Jun 29, 2017 at 11
