A data transfer method for autonomous vehicles includes autonomously positioning a vehicle to achieve an alignment condition in which a vehicle-mounted directional antenna coupled to a vehicle radio is aligned with a curbside antenna coupled to a curbside radio. A peer-tip-peer radio link is established between the vehicle radio and the curbside radio, and data is transferred from the vehicle radio to the curbside radio using the peer-to-peer radio link. The peer-to-peer radio link may be a millimeter-wave radio link. Data is transferred at high speed, for example at least tens of gigabits per second or even hundreds of gigabits per second. The vehicle may be an electric vehicle, and electric charging of the vehicle may be performed while transferring the data. In one embodiment, the vehicle is configured to proceed to a recharging location when a given low state of charge is reached. Transferring data may be performed at a rate such that during recharging from the low state of charge to a target state of charge, all data to be transferred from the vehicle is transferred, or at least a terabyte of data is transferred.

Vehicle to infrastructure autonomous data backhaul

A transmitter or transceiver assembly includes at least one transmitter module. The transmitter module includes a matrix of transmitter integrated circuit die and a matrix of antennas, each antenna being coupled to a respective transmitter integrated circuit die. The matrix of antennas is configured to reduce interaction between signals transmitted by respective ones of the antennas.

High bandwidth scalable wireless near-field interface

A wireless data transceiver comprises a voltage controlled oscillator configured to generate a first time-varying signal. The transceiver further comprises an antenna configured to receive a signal wirelessly over a network. The transceiver further comprises an amplifier configured to amplify the signal. The transceiver further comprises a frequency mixer coupled to the voltage controlled oscillator and the amplifier. The frequency mixer is configured to generate a second time-varying signal based on the first time-varying signal and the amplified signal. The transceiver further comprises a power detector configured to measure a characteristic of the second time-varying signal. The transceiver further comprises an automatic gain control circuit coupled to the power detector and the amplifier. The automatic gain control circuit is configured to adjust operation of the amplifier based on the measured characteristic, a minimum power setting, and a maximum power setting.

Millimeter-wave mixed-signal automatic gain control

A wireless data transceiver comprises a local oscillator configured to generate a first time-varying signal of a first frequency at an output of the local oscillator. The transceiver further comprises a local oscillator interface circuit coupled to the local oscillator. The local oscillator interface circuit is configured to generate a second time-varying signal of the first frequency with negative conductance at an output of the local oscillator interface circuit. The negative conductance is generated based on capacitive degeneration. The transceiver further comprises a frequency mixer coupled to the output of the local oscillator interface circuit. The frequency mixer is configured to generate a third time-varying signal of a second frequency based on the second time-varying signal.

Compact and low-power millimeter-wave integrated VCO-up/down-converter with gain-boosting

A method includes providing a highly linear front end in a Radio Frequency (RF) receiver, implementing a high Effective Number of Bits (ENOB) Analog to Digital Converter (ADC) circuit in the RF receiver, and sampling, through the high ENOB ADC circuit, at a frequency having harmonics that do not coincide with a desired signal component of an input signal of the RF receiver to eliminate spurs within a data bandwidth of the RF receiver. The input signal includes the desired signal component and an interference signal component. The interference signal component has a higher power level than the desired signal component. The method also includes simultaneously accommodating the desired signal component and the interference signal component in the RF receiver based on an increased dynamic range of the RF receiver and the high ENOB ADC circuit provided through the highly linear front end and the high ENOB ADC circuit.
