Hi Paul, I do not have one. Do you implemented them before?

Best Paul 2011/12/15 Phone Naing MYINT <phonenaing.my...@sg.panasonic.com<mailto:phonenaing.my...@sg.panasonic.com>> 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 symbols. After that I’m getting all rubbish data. I think the problem with my RTL implementation is not good enough bit-resolution (unlike implementation on PC). Currently I’m using 15-bits resolution for decimal part. Anyone has any suggestion ?
