The polar modulator further includes a modulation means which is implemented to combine an amplitude modulation signal derived from the amplitude information with the phase-locked loop output signal to generate the polar-modulated signal. The polar modulator further includes a control value generator which is implemented to high-pass filter an amplitude signal derived from the amplitude information, to obtain a high-pass filtered amplitude signal, wherein the control value generator is implemented to combine the high-pass filtered amplitude signal with a phase signal based on the phase information to generate the control value signal representing the control value.

摘要： One embodiment of the present invention relates to a communication system having a digital to analog converter, a first input, a summation component, a compensation filter, and a compensation unit. The converter is configured to receive a first signal. The first input is configured to receive a phase modulation signal. The compensation filter generates a filtered frequency deviation signal to mitigate frequency distortions, such as those from a digital controlled oscillator. The compensation unit includes one or more inputs and is configured to generate a correction signal according to the filtered frequency deviation signal and the first signal. The correction signal at least partially accounts for estimated distortions of the phase modulation signal from the amplitude modulation path and mitigates frequency induced distortions. The summation component is configured to receive the phase modulation signal and the correction signal and to generate a corrected phase modulation signal as a result.

摘要： A method and an arrangement for processing a received signal which comprises phase-shift modulated or amplitude-quadrature modulated part-signals which are transmitted in a plurality of different frequency bands, wherein the received signal is processed in a plurality of stages in succession, by multiplying all the input signals to each of the stages by two mutually orthogonal signals in each case to form two intermediate signals in each case, wherein the intermediate signals from one stage in each case act as the input signals to whichever is the succeeding stage in the particular case and the received signal acts as the input signal to the first stage, and wherein an in-phase and/or an quadrature component of the individual part-signals in the different frequency bands are determined from the intermediate signals from the last stage. Parallel, simultaneous reception of a plurality of frequency bands can be implemented relatively easily in this way.

摘要： The invention is directed to a phase locked loop with a ΣΔ modulator. A multimodulus divider in the feedback path of the PLL is actuated by the ΣΔ modulator. The latter has a design which can be described by a complex transfer function H(s) in the Laplace plane, said transfer function having a complex-conjugate pair of pole points. The arrangement allows a significant reduction in the noise in critical frequency domains and hence allows adherence to transmission masks based on radio specification even when the PLL bandwidth is as large as the modulation bandwidth.
