摘要： 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.

摘要： A wireless communication system can comprise two or more antennas that interfere with one another via free space coupling, surface wave crosstalk, dielectric leakage, or other interference effect. The interference effect can produce an interference signal on one of the antennas. A cancellation device can suppress antenna interference by generating an estimate of the interference signal and subtracting the estimate from the interference signal. The cancellation device can generate the estimate based on sampling signals on an antenna that generates the interference or on an antenna that receives the interference. The cancellation device can comprise a model of the crosstalk effect. Transmitting test signals on the communication system can define or refine the model.

摘要： Disclosed is a gain boosting technique for use with millimeter-wave cascode amplifiers. The exemplary technique may be implemented using a 0.18 μm SiGe process (FT=140 GHz). It has also been shown that the technique is effective for CMOS processes with comparable FT. An exemplary gain-enhanced cascode stage was measured to have higher than 9 dB gain with a 1-dB bandwidth above 6 GHz with a DC power consumption of 13 mW. In addition, one cascode stage without gain boosting may be cascaded with two gain-boosted cascode amplifier stages to implement a three-stage LNA. The measured stable gain is higher than 24 dB at 60 GHz with a 3-dB bandwidth of 3.1 GHz for 25 mW of DC power consumption. It is believed that this is the first 60 GHz LNA with a higher than 20 dB gain using a 0.18 μm SiGe process.

摘要： Antennas of broadband and multi-band operation are presented. A broadband planar antenna includes two inverted-L antennas (ILAs) facing each other across a gap. One of the ILAs is input fed, and the other is electromagnetically coupled. The positioning of the gap affects the bandwidth. A dual-band planar antenna includes two ILAs facing each other across a gap with one of the ILAs being input fed, and the other being coupled. This dual-band planar antenna also includes a monopole antenna disposed between the two ILAs. A triple-band planar antenna includes two ILAs facing each other across a gap with one of the ILAs being input fed and the other IPA being coupled. This triple-band antenna also includes a monopole antenna disposed between the two ILAs, and a conductor extending horizontally from the monopole antenna towards, but not reaching the coupled ILA. Another dual-band antenna includes an inner cut loop antenna encompassed by an outer cut loop antenna. Each of the cut loop antennas includes two ILAs with one of the ILAs being input fed and the other being coupled.

摘要： 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.
