摘要： An electronic arrangement and method for providing a signal characterized by reduced phase noise having a signal source for providing a stimulus signal, a modulator coupled to the signal source for generating a modulated signal as function of the stimulus signal and a local oscillator signal, and a mixer combining the stimulus and modulated signals to generate a mixed signal that includes a component characterized by a mathematical difference of the stimulus signal and the modulated signal. The modulated signal substantially identical to the stimulus signal and being offset by a frequency of the local oscillator signal, so that the difference component of the mixed signal results in a local oscillator signal wherein the stimulus signal phase noise generated by the signal source has been mathematically cancelled.

摘要： An FM transmitter operates at low power by maintaining a substantially constant transmit voltage over the FM frequency band. A transmit signal strength indicator (TSSI) is provided at the output of the FM transmitter to measure the power at the output of the power amplifier. The TSSI generates a power control signal indicative of the output power and inputs the power control signal to the baseband processor. The baseband processor generates gain control signals to control the gain of various analog stages of the FM transmitter based on the power control signal.

摘要： Methods of reducing spectral leakage due to I-Q imbalance within a transmitter are disclosed. The method includes the transmitter receiving a data stream of coefficients of a multi-carrier modulation signal. The data stream is pre-processed by processing a set of the coefficients that correspond with selected notch frequencies to reduce the effects of I-Q imbalance of the transmitter, wherein at least a portion of the set of coefficients corresponds to non-symmetrical notch frequencies. The pre-processed data stream is multi-carrier modulated. The multi-carrier modulated pre-processed data stream is I-Q modulated before transmission.

The process includes detecting a DC offset signal by averaging sampling values of returned I/Q digital signals; detecting a gain compensating signal using a maximum value in a period of the I/Q digital signals of which the DC offset is compensated; and detecting a phase compensating value of the I/Q digital signals on the basis of sum of absolute values for differences between the gain compensated I-digital signals and Q-digital signals, and remove phase error, gain error and DC offset of the inputted digital signal sequentially to compensate the AQM error.
