Method and apparatus for signal-to-noise ratio calculation in radiocommunication systems using measurements of supervisory audio tones |
摘要 |
Methods and systems for measuring signal noise of supervisory audio tones (SATs) in radiocommunication systems are disclosed. Exemplary embodiments involve extracting a real component from a received SAT signal, removing the SAT signal portion and examining the remainder to determine a noise component present in the SAT. The noise component can be compared with a signal strength measurement to obtain a signal-to-noise ratio. |
