uhd is the hardware driver for ettus products http://code.ettus.com/redmine/ettus/projects/uhd/wiki gnuradio is the modulation tool kit + examples. Tom has ported all of the example to uhd in the next branch. gr-uhd is a component in gnuradio that provides usrp source and sink blocks. This is the gateway between gnuradio and the hardware. usrp/gr-usrp is the legacy driver that only support usrp1 > Do you mean that our old ofdm codes that work on USRP1 cannot be used > anymore? > We are working on Non-Contiguous OFDM and our previous codes can disable > some subcarriers on USRP1. > Because we want to do FFT on FPGA, we change to use USRP E100, but codes on > the host are useless now? > You will have to change the block that is instantiated to be a uhd usrp source or sink. There is no reason that rest of your modulation/demodulation chain or mac layer would have to change.
