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.

Abstract: A method of controlling a hybrid phase-locked loop may include generating a first control signal based on an offset signal and a second control signal and determining a difference between the first and the second control signals. The method may further include adjusting a value of the offset signal based on the difference between the first and the second control signals to drive a level of the first control signal to a level of the second control signal. The method may further include determining when the level of the first control signal crosses the level of the second control signal. After the level of the first control signal crosses the level of the second control signal, the method may include adjusting the value of the offset signal based on a number of occurrences of the level of the first control signal crossing the level of the second control signal.
