Hi all, I am using the trunk repository with revision no. 11025. I am presently experimenting on ofdm. The given code is working fine on the USRP setup. Here we specify the center frequency at which the ofdm signal is going to be transmitted. I have a few questions on this: 1) Is this the center frequency of the sub-carrier of a particular channel? If so, what is the bandwidth used? 2) If not, how the sub-carrier is differentiated from the channel? How many sub-carriers are supported? 3) Is it possible to switch to a different frequency at runtime? 4) The modulation parameter is the modulation technique defined for a particular sub-carrier, right? If so, can we also define a different modulation technique to be used at runtime once we switch to a different frequency? 5) The preamble defined for the packets - are they standardized? I mean to say, any ofdm packet will be having the same preamble? 6) Why the interpolation/decimation values need to be specified for this experiment alone? This is not the case for other examples given in 'gnuradio-examples' folder.
Please help me figure out the answers for these. It will help in proper understanding of ofdm implemented on gnuradio. Shesh _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
