IMPROVED FM TRANSMISSION SYSTEM AND METHOD |
摘要 |
<p>An RF transmission system comprises an RF transmitter receiving a base band media signal and generating a broadcast signal on a broadcast frequency. The broadcast frequency may be one of a plurality of transmission frequencies within a frequency band. A radio data control module periodically performs an interference detection measurement to determine whether an interfering signal from a remote transmitter exists at the broadcast frequency. An open frequency is selected if an interfering signal from a remote transmitter exists at the broadcast frequency. The open frequency may be one of the plurality of transmission frequencies wherein RF interference is within predetermined acceptance criteria. The RF transmission system transmits an identification of the open frequency on the broadcast frequency and, following such transmission, switches the broadcast frequency to such open frequency.</p> |
