輸 出 O U u a 的意義當運行 gnu radio 程序時,會有時看見 O U u a 字符出現在屏幕上。這一般當數據從 USRP 到 PC 機數據輸到硬件的時候PC數據速率跟不上。
- 輸 出 "O" "U" "u" "a" 的意義
"u" = USRP
"a" = audio (聲卡)
"O" = overrun (PC 無法同步地接受來自 USRP 或 聲卡的數據 - PC not keeping up with received data from usrp or audio card)
"U" = underrun(PC 無法快速的提供數據 - PC not providing data quickly enough)
aUaU == audio underrun (PC 無法快速地給“漏”- 聲卡提供數據 - not enough samples ready to send to sound card sink)
uUuU == USRP underrun (PC 無法快速地給“漏”- USRP提供數據 - not enough sample ready to send to USRP sink)
uOuO == USRP overrun (USRP 採樣掉鏈源於它沒有及時準備到位 - USRP samples dropped because they weren't read in time)
