Abstract

A transmitting apparatus for generating a phase-modulated carrier signal with on-off keying (OOK) includes a coding circuitry for receiving binary digital data and generating an on-off keying (OOK) signal representing the binary digital data. The coding circuitry generates a phase modulation control signal for controlling a phase modulation of a millimeter wave carrier signal based on the on and off pattern of the OOK signal. The apparatus also includes a phase modulation circuitry for applying the phase modulation to the millimeter wave carrier signal based on the phase modulation control signal to generate a phase-modulated carrier signal, and a power amplifier for generating, based on the OOK signal and the phase- modulated carrier signal, an amplified phase-modulated carrier signal with OOK. The apparatus includes an interface to transmit the amplified phase-modulated carrier signal with OOK to a receiving apparatus via a millimeter wave communication link.

Description

technical field [0001] Embodiments of the present disclosure relate generally to the field of electronic devices, and more particularly to applying phase modulation to millimeter waves with on-off keying (OOK) for spectrum control. Background technique [0002] Extremely high frequency (EHF) is the radio frequency part of the electromagnetic spectrum. For example, EHF has a frequency range from 30-300 gigahertz (GHz). Radio waves in this frequency band have wavelengths from 1 to 10 millimeters, which is why this radio wave has the name millimeter band or millimeter wave. Due to the shorter wavelength, this frequency band allows the use of smaller antennas than would be required for similar situations in lower frequency bands to achieve the same high directivity and high gain. High directivity enables more efficient use of spectrum for point-to-point communications, inter-satellite links, point-to-multipoint communications, etc. [0003] In particular, signals in the 57-64...
