[Discuss-gnuradio] System overrun after short time

[Luong Tan Phong]

Hi Lists,

I wrote a program in C + + use gnuradio library to demodulate some signals. The program works well with the low data rate signal (below 20 Ksymbols/s). With higher data rate signal: 200 Ksymbols/s, the program works well for a few minutes then the console window will appear the letters 'O' continuously and data after demodulation was wrong. With 1 Msymbols/s signal, the system can operate well over 1 minute.

Could you help me to solve the problem, please?

Thank you.

Best regards,

Phong.
