摘要
A system and method for dynamically optimizing occupied bandwidth of a direct modulated FM radio comprises a remote receiver that periodically monitors the received output of a local transmitter and compares the received output occupied bandwidth to a reference level. If the monitored level of the demodulated signal unacceptably exceeds the reference level an error message is developed and sent back to the local transmitter to cause the output of the local transmitter to be adjusted to more closely conform to the desired spectrum output mask. An alternative embodiment is also disclosed in which temperature and operating frequency are monitored at the local transmitter and a correction factor appropriate for that operating temperature and frequency are applied.
