[Discuss-gnuradio] edit packet content in benchmark

2013-06-24 Thread yeran
Hi everyone, In benchmark, the packet is 23-byte long, inclues preamble, access code, header, payload, crc, and 'x55'. Now I want to add a one-byte flag after the header. I changed the packet_utils.py make_packet block, add a flag when form the new packet. And changed the header length to 9. H

Re: [Discuss-gnuradio] How to integrate a specific number of vectors element-wise in gnuradio?

2013-06-24 Thread Marcus D. Leech
Dear Gnuradio enthusiasts, Short version: Does someone have a good approach to average a specific (but large) number of vectors together element-wise with the exactly same relative weight? Say I want the two vectors [1,2,3,3] and [1,2,3,4] coming one after another giving the output [1,2,3,3.5]

Josh, I'm curious about how it tune the LO in USRP. Does it control the LO via 'post_msg(CTRL_PORT,pmt.pmt_string_to_symbol('usrp_sink.set_center_freq')'? Thanks. 2013/6/9 1:44, John Malsbury wrote: Jay, Thanks for checking out pre-cog. I'm not sure what "algorithm" you'd call it
