    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.

    摘要: Aspects of a method and system for simultaneous signal transmission on multiple selected frequencies may include generating from a single baseband signal, a plurality of radio frequency transmission signals each at a different radio frequency, wherein the single baseband signal comprises an in-phase signal component and/or a quadrature signal component. The single baseband signal, to generate said plurality of radio frequency transmission signals, may be modulated in a single radio frequency transmission chain, the radio frequency transmission chain comprising intermediate frequency modulation and radio frequency modulation. The plurality of radio frequency transmission signals may be a radio frequency signal and a corresponding image frequency signal, based on the intermediate frequency modulation and the radio frequency modulation. The signals resulting from the intermediate frequency modulation and the radio frequency modulation may be filtered to preserve the radio frequency signal and the corresponding image frequency signal.

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 method and system is provided for enabling communication, where a FM radio system including an integrated FM radio transmitter and FM radio receiver may use an in-band FM or out of band transmitter to communicate a dynamically generated list with alternate local FM channels to an in-band or out of band receiver of another FM radio device with a FM radio receiver. The generated list of local FM channels may be ranked according to the least neighboring channel interference and may be selected for tuning the FM radio device. The FM radio system and the FM radio device may both scan to generate a substantially matched list of local FM channels. In response to detecting a new signal of a transmitted channel by the FM radio system, the FM radio device may tune to the same channel using an open loop, closed loop or semi-open loop method.
