Re: [Discuss-gnuradio] how to implement auto-correction of sample rate in flow graph ?

2013-12-14 Thread Artem Pisarenko
Hi Marcus, Everything you said I'm already thought about during last days and finally came to conclusion, that buffer estimation model is the only reliable (it solves issue directly by its nature) and universal one (many drivers provide required functions in their API). Since it involves control l

I i try that DQPSK schema myself, but i notice that in your image you have Bits per symbol in packet encoder set to 4, but the help of packet encoder says 2 for DQPSK. I try 2, and i get no errors until the end, probably because of file buffering. --- sent.hex2013-12-14 10:11:41.308775941 -080

[Discuss-gnuradio] UHD and libusrp driver writing for RFX dpughterboards, RFX1900

2013-12-14 Thread Robert Light
Hi, I have an RFX1800 board with modifications allowing it to work in 900MHz and 1800MHz band. What I find annoying is that if I want to use it in both bands, each time I have to reprogram EEPROM. Life would be a lot easier if I had one driver that tunes the board in the whole freq range 750-2100

Hi Wayne I agree with every point you mentioned in your reply. For the variable Bits per symbol, that was a mistake since I previously used it to test QAM. So, have you tested QAM? In my test, the two files didn't match as discussed in my previous post. Just curious about why this mismatch can ha

Hello GNU Radio enthusiasts, some time after the GNU Radio 3.7 release I started to move the code for 'gr-lte' to the new API. Besides moving it to the new API, I wanted to clean up code and rework a lot of tests. Thus, the whole transition took a lot of time and work. Now, all current blocks are

There isnt any QA code for QAM modulator or demodulator. They do not work for me. I think if they worked, then their would be QA code. On Sat, Dec 14, 2013 at 12:08 PM, Henry Jin wrote: > Hi Wayne > > I agree with every point you mentioned in your reply. For the variable > Bits per symbol, that
