摘要：
A system and method for demodulating signals are disclosed. In a particular embodiment, the method includes receiving a signal at an input and determining a first noise estimate of the signal. The method also includes providing a first output indicating a second noise estimate of the signal at a primary carrier frequency and providing a second output indicating a third noise estimate of the signal at a secondary carrier frequency.
