摘要： In a wireless communication system which may include a mobile device having an integrated FM radio transmitter and a FM radio receiver, a geographic location of the mobile device may be determined. A FM channel map may be determined based on the location and the FM radio transmitter may be configured for transmitting FM signals based on the FM channel map, which may include a list of ranked FM channels. The geographic location may be acquired from received RDS or RBDS signals, received GPS signals, other received wireless signals, and/or from user data. Channel spacing, channel offset and/or frequency band may be determined for the FM channel map. A frequency for transmitting FM signals via the FM radio transmitter may be selected based on the determined FM channel map. The FM radio receiver may also be configured for receiving FM signals based on the determined FM channel map.

摘要： A plurality of digital audio signals from a plurality of sources utilizing different clocks may be processed and transmitted via an FM transmitter. The plurality of signals may have different sample rates which are converted to one same sample rate by a plurality of rate adapters. The plurality of rate adapters may be clocked at one same sample rate. The energy levels of the signals may be adjusted relative to one another and as a group. Energy level adjustments may improve FM modulation signal characteristics and audible energy levels for an end listener. The plurality of digital audio signals may be combined into one composite signal and FM modulated in the digital domain. The FM modulated signal may be converted to analog signal prior to being filtered, amplified and coupled to an antenna for transmission.
