[Discuss-gnuradio] Using external clock with USRP2/WBX

Hi all, I'm trying to use the external clock input of the usrp2 with WBX in receive mode. Unfortunately after processing the recorded signal there is still a clock drift despite the fact i'm using a GPS reference clock. So i suppose that i'm making something wrong. 1) I'm using a square 10 Mhz ref

[Discuss-gnuradio] OFMD TX and RX

Hello everybody, I' am trying to test and understand the OFDM Modulation implemented in GNU Radio. I'm using the deafult values, fft_lenth=512, occupied_tones =200, cp_length= 128 and bpsk modulation, besides, I'm using a RFX900 Daughterboards on USPR and I'm connecting the TX and RX with a coax

Re: [Discuss-gnuradio] complex vector output of a block

Well, I think I used io_signature correctly. And, as I am using gr_sync_block, I dont need to worry about forecast, set_output_multiple or gr_sync_decimator. (I hope this understanding is correct?!) I have read the " how to write a block" and followed what's in there, but if you guide me to bette
