[Discuss-gnuradio] tx frequency changing by clk_divider

[Yan Nie]

Dear all,


I'm trying to use clk_divider block to down the frequency of baseband PN code in project gr-sounder to 32kHz. The time quest analysis of the verilog code shows the result is correct. After the FPGA bitstream loaded,however, the waveform of the signal still contains some high frequency component (noise) but much more better than PN code spread 32MHz. 


The major problem of the frequency decreasing is the transmitting signal from the antenna doesn't show the result of BPSK modulation in the waveform of the signal. Could you please give some suggestions about what the problem?


Thanks in advanced.


Regards,
Yan
