Abstract: A method and system for processing channels in a FM communication system are provided. The FM communication system using the method or program may include adjusting a tuning frequency of a FM receiver for scanning and detecting an FM channel based on one or more of knowledge of location of said FM receiver, received signal strength indicator (RSSI), and/or carrier error of a related FM signal. Frequency offsets and channel spacing of the detected FM channels may be derived based on a self measurement routine. The aforementioned information may be preprogrammed, updated from a previous scan, or from external inputs to configure the receiver for subsequent selective tuning.

Abstract: According to one embodiment, an electronic device, for example, a portable electronic device such as a cellular telephone, a portable navigation device, a personal digital assistant (“PDA”), or an MP3 player, includes a GPS receiver configured to receive GPS coordinates. The GPS coordinates are sent to a CPU that is configured to retrieve location-based information from, for example, a memory device or a cellular module in the electronic device. An FM transmitter module is configured to encode and transmit the location-based information as encoded text, for example encoded RDS text, to an FM receiver in a vehicle. The RDS text can then be displayed on a display panel of the FM receiver. In addition to the encoded RDS text, audio signals from the FM transmitter module can be transmitted to the FM receiver for broadcast by a speaker of the FM receiver contemporaneously with the display of the RDS text.
