http://pwnhome.files.wordpress.com/2011/04/simple_transceiver1.png see carefully....... it has a gmsk modulator in the bottom.u can make the bottom modulator part in another pc
benchmark programs are quite good to start with... u can type benchmark_ofdm.py -h to see all the parameters u can play with. waqasme wrote: > > And sorry to mention in the last mail that i will be suing USRP 1 . > > waqasme wrote: >> >> Hi Sumit, >> Thank you so much for your quick response. yah i understand what your >> saying and i am trying to understand this document but it doesnot help >> much .
