Problems solved by technology

However, since typical radio signal frequency bands in mobile communication networks can lie in the carrier frequency range from 2 GHz to 3 GHz (corresponding to wavelengths between 10 cm and 15 cm), delay lines are useful in building compact communication devices (e.g., hand-held mobile device) tends to be too large in terms of circuit integration and miniaturization space requirements

example 1

[0073] Example 1 is an electronic circuit for generating a delayed radio signal for use in a radio communication device. The radio communication device is configured to provide a transmit baseband signal in a baseband, up-convert the transmit baseband signal into a transmit radio signal in a radio frequency band, transmit the transmit radio signal in a radio frequency band, and simultaneously receive a receive signal in the same radio frequency band. radio signal. The electronic circuit may include: a delay circuit configured to delay a copy of the transmitted baseband signal for a period of time to generate a delayed baseband signal; an upconversion circuit configured to spectrally shift the delayed baseband signal to a radio frequency band to generate a delayed radio signal and an output circuit configured to output the delayed radio signal for the cancellation circuit to cancel the delayed radio signal from the received radio signal.

Description

technical field [0001] Various aspects of the disclosure relate generally to wireless communication technologies. Background technique [0002] Radio communications may take place between a communications device and a communications partner, which may be a base station in a cellular communications network. Conventional designs for two-way communication include time-domain multiplexing and frequency-domain multiplexing, that is, the transmission and reception of radio signals can be performed in different time frames or in different radio frequency bands to avoid communication devices and communication partners Interference between radio signals. [0003] The use of two different radio frequency bands allows full-duplex communication, i.e. two communication partners can send radio signals continuously without signal interference. However, the most limited and valuable resource in radio communications is the band of spectrum used as a communication channel. Therefore, effor...
