Hi, All, In my current design, frequency hopping is designed to happen over 32MHz bandwidth, as fast as possible. (although I admit that by using USRP1, it may not be that fast as I expected). However, I am not very clear about how to do so.
I checked the implementation of bluetooth (gr-bluetooth-0.4) but did not get any ideas/examples/instances of FH. (Someone interested in bluetooth is recommended to have a look at this.) I did create a piece of code (as shown below) following usrp_spectrum_sense.py. However, .tune() gives me a huge and unfavorable delay time. Is there any better way to impalement FH? ..... def set_freq(self): target_freq = 900e6 + 3.2e6 * random.randint(1, 10) self.rx.tune(0, self.rx_subdev, target_freq) while 1: time.sleep(0.3) # Wait fg.set_freq() ..... BTW, I read considerable messages from the Mail Archive, and realized that inband signaling and m-blocks is an ideal solution for FH. Does anyone have any examples/codes/documents/suggestions regarding the inband signaling and m-blocks for FH?
