    • 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.
    • 在可以包括具有集成FM无线电发射机和FM无线电接收机的移动设备的无线通信系统中,可以确定移动设备的地理位置。 可以基于该位置来确定FM频道映射,并且FM无线电发射机可以被配置为基于可以包括排列的FM频道的列表的FM频道映射来发送FM信号。 可以从接收的RDS或RBDS信号,接收的GPS信号,其他接收的无线信号和/或从用户数据获取地理位置。 可以为FM频道映射确定信道间隔,信道偏移和/或频带。 可以基于所确定的FM频道映射来选择经由FM无线电发射机发送FM信号的频率。 FM无线电接收机还可以被配置为基于所确定的FM频道映射来接收FM信号。
