[Discuss-gnuradio] Costas loop and M&M algorithm on FPGA

Hi, Anyone here implemented freq/phase correction and symbol timing correction in USRP's FPGA? Recently I implemented Costas loop and Muller & Mueller algorithm in RTL by referring the gnuradio code. Now I'm testing it on FPGA. I can get correct demodulated data(DQPSK) at initial few thousand

[Discuss-gnuradio] Monthly Developers call

We will be having our monthly call tomorrow. Same time and details as usual. http://gnuradio.org/redmine/projects/gnuradio/wiki/DevelopersCalls I'll try to post an agenda, but I don't have much right now. Mostly, we are looking to planning what features we're looking for in the 3.6 release. Than

Hi there, I made some decent progress but refining the parameters for the benchmark_tx.py and benchmark_rx.py without no errors. However, I can only transmit but I could not receive anything at the receiver side. Could somebody suggest what might be the problem? I tried to work it but still c

[Discuss-gnuradio] UHD Calibration continued.

I have been looking more at the performance of the udh_cal_* routines to try and understand the operation of my N210 and the SBX card. I found the cal files that I had previously generated and moved them into a separate directory to prevent the UHD driver from finding them. From the documentation

Re: [Discuss-gnuradio] Importing Grblock or not?

Hi guys! I have problems with writing a processing block in python. I looked at the examples here http://gnuradio.org/redmine/projects/gnuradio/wiki/WriteBlocksInPython but when I try to create a new class that inherits gr.sync_block (or any other from the example) I get this output: Traceback (m

[Discuss-gnuradio] duration of uhd_rx_cfile script

Hello all, I just measured the time the execution of uhd_rx_cfile.py takes all together. I used N=2, samp-rate=1M and the rest was left to the default values. In theory the taking of the samples should take T=N/B=20ms but I had to discover that the whole process is taking about 2s. Do
