-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey all,
I'm trying to receive, and send, traffic on a fixed but unknown carrier frequency within the passband of the USRP. That is, there are many communication bands, but transmissions happen on only one of k channels. The trivial approach is to have one translating filter, with a channel select filter, for each channel and hook them all in parallel to the receive chain. Then to respond I can have k different callbacks, one for each channel, which will cause response packets to be sent to one of k different transmit paths corresponding to the different channels. Does anyone see a more elegant way to do this? I can imagine that using an FFT I can discover on which channel a transmission occurs, but AFAIK there's not a good way for one GNU Radio block to tune another (e.g. tuning the xlating filter with the FFT). Thanks!
