  • System and method for station detection and seek in a radio receiver
    Patent number: 7920839
    Abstract: A system for detecting a broadcast channel in a radio receiver includes a receive signal strength indicator (RSSI) element configured to develop an RSSI signal that is representative of a power in a desired channel, a switchable bandwidth channel select filter having a power detector configured to compare a power output of the desired channel and at least one channel adjacent to the desired channel to develop a signal to adjacent channel power ratio (SACPR) signal that is representative of the noise in the desired channel, and a seek element configured to determine whether the RSSI signal is greater than a predetermined RSSI threshold and configured to determine whether the SACPR signal is greater than a predetermined SACPR threshold.
