摘要： Embodiments of the present invention create a circuit having a digital-to-time converter with a high-frequency input for receiving a high-frequency signal, a digital input for receiving a first digital signal, and a high-frequency output for the provision of a chronologically delayed version of the HF signal. In addition, the circuit has an oscillator arrangement for the provision of the high-frequency signal, having a phase-locked loop for adjusting a frequency of the high-frequency signal. The digital-to-time converter is designed to chronologically delay the received high-frequency signal based on the first digital signal received at its digital input.

摘要： One embodiment covers an apparatus for generating a transmission signal. The apparatus may include a signal generator that generates a first signal with a first frequency spectrum comprising a carrier frequency; a power control unit that provides a power information signal which represents a signal level of the transmission signal residing at the carrier frequency; a first signal shaper for noise-shaping the first signal based on the power information signal to form a second signal which has a noise component in at least one frequency range remote from the carrier frequency, the noise component of the second signal being from one or more signal components associated with the carrier frequency; and a signal output that provides the second signal in the form of a transmission signal.

The transceiver also includes a controllable coupling device configured to couple an output of the first receive amplifier to an input of the frequency conversion device on the second signal path, and a control circuit configured to provide a control signal to the coupling device for selectively combining signals delivered by the first and second receive amplifiers in the correct phase based on a parameter which is derived from a signal present at the first connection or second connection, or both. The parameter derived from the received signal represents whether a signal strength of the received signal or a signal quality of the received signal exceeds a first predetermined threshold.

摘要： A transceiver arrangement includes a first receive path with a first connection and a first receive amplifier, and a second receive path with a second connection, a second receive amplifier, and a frequency conversion device. A controllable coupling device is configured to couple an output of the first receive amplifier to an input of the frequency conversion device on the second signal path. Furthermore, the transceiver arrangement includes a control circuit configured to deliver a control signal to the coupling device for combining signals delivered by the first and second receive amplifier in the correct phase based on a signal supplied by the receive paths. This achieves receive diversity wherein, on the one hand, additional external components are no longer necessary and, on the other hand, adequate signal quality is ensured even with a simultaneous transmit process of the transceiver arrangement.
