Abstract
A method of generating a transmission signal may include mixing a baseband signal assigned for transmission within a narrow frequency range (“assigned narrow frequency range”) included in a wireless communication channel to produce a shifted signal. The shifted signal may have a shifted frequency that is based on a shift from the assigned narrow frequency range toward a center frequency of the wireless communication channel by a frequency offset. The method may further include shifting a modulation frequency of a modulating signal toward the assigned narrow frequency range frequency range and away from the center frequency by the frequency offset. Additionally, the method may include mixing the shifted signal with the modulating signal to produce a transmission signal having a transmission frequency within the assigned narrow frequency range.
