摘要： According to the invention, a Cartesian control means (16) comprising a phase rotator (50) and a phase adjuster (52) is provided. With a method and a device according to the invention, a system is provided that is unconditionally stable with respect to non-phase alignment, regardless of input power changes, temperature and component ageing. No certain conditions need to be placed upon the control system to ensure stability, i.e. the system is non-obtrusive and requires no off-line calibration. The inclusion of the phase rotator (50) and phase adjustment techniques into the Cartesian control system makes this possible.

摘要： An RF transmitter employs negative feedback to reduce non-linearities in power amplifying means (18 to 21) and, since the transmitter received as input I and Q components, a Cartesian Loop is provided, by means of which a signal derived from the output of the amplifier by a probe (22) is split into de-modulated I and Q components in order to provide feedback signals at (27 and 28). Unfortunately the negative feedback cannot correct for errors in the feedback loop itself, and component imperfections introduce a DC offset into the feedback loop. The modulation is suppressed carrier but the DC offset re-introduces the carrier. The invention provides a method of reducing the DC offset to reduce the carrier breakthrough by injecting known DC offsets into the I and Q inputs and measuring the resulting ripple in the output of the power amplifier means corresponding to the re-introduced carrier, enabling calibration offset DC levels to be calculated and injected into inputs (27, 28).

摘要： Various embodiments provide for systems and methods for signal conversion of one modulated signal to another modulated signal using demodulation and then re-modulation. According to some embodiments, a signal receiving system may comprise an I/Q demodulator that demodulates a first modulated signal to an in-phase ("I") signal and a quadrature ("Q") signal, an I/Q signal adjuster that adaptively adjusts the Q signal to increase the signal-to-noise ratio (SNR) of a transitory signal that is based on a second modulated signal, and an I/Q modulator that modulates the I signal and the adjusted Q signal to the second modulated signal. To increase the SNR, the Q signal may be adjusted based on a calculated error determined for the transitory signal during demodulation by a demodulator downstream from the I/Q modulator.

摘要： The present invention provides a method and apparatus for detecting and compensating for transmitter phase shift in a radio transmitter. A local oscillator generates a local oscillator signal. A modulator such as an I/Q modulator modulates input signals onto the local oscillator signal to generate a forward signal. That forward signal is amplified and otherwise prepared for transmission via an antenna. The transmitted signal is detected, and a phase adjuster substantially continuously detects and cancels undesired phase shifts in the detected signal caused by elements in the radio chain. A specific, example embodiment of the present invention is provided in a Cartesian feedback system wherein the phase of the feedback signal is detected and aligned with the phase of the original modulated signal, providing uncorrupted I and Q baseband feedback signals. Another specific example embodiment of the present invention is to a diversity radio receiver. Received signals from the diversity antennas are processed to determine the phase difference between the two signals. The phase of one of the received signals is rotated to match the phase of the other, and thereafter, the diversity received signals are added together before demodulating the originally transmitted signal. Such additive combination of diversity received signals under same or similar received signal level conditions when two signals are aligned in phase considerably improves the signal to noise ratio of the received signal.
