Full-Duplex OFDM Radar with LTE and 5G NR Waveforms

Teams of Finnish engineers explored the principles, implementation challenges, and performance of OFDM-based radars, with particular focus on 4G LTE and, especially, 5G NR mobile network base stations. They showed that properly tailored analog/RF and digital SI cancellation solutions are key technical ingredients for practical deployments, particularly for detecting static and slowly moving targets.

28-Gb/s 60-GHz Bidirectional 802.11ay Transceiver

A new 60-GHz CMOS IEEE 802.11ay transceiver applies an area-efficient bidirectional technique, sharing interstage passive components to reduce manufacturing costs and cut the transceiver footprint to just 0.96-mm². Measured RX noise is 5.4 dB; TX-mode error vector magnitude is -26 dB with output power of -4.2 dBm. Maximum data rate is 28.16 Gb/s in 16-QAM.

A 1-Mb/s BLE Uplink for Brain-Computer Interface

Wireless brain-computer interfaces (BCIs) must minimize both thermal dissipation into tissues and battery size and weight. A new backscatter Bluetooth Low Energy (BLE)-compatible backscatter communication uplink for the NeuroDisc BCI works with unmodified BLE devices such as PCs, smartphones, and tablets. It consumes just under 200 pJ/bit, less than 2% of the energy commercially available BLE transmitters use, while single-sideband BLE backscatter increases available channel power by +3 dB.

Wireless Time Transfer With Subpicosecond Accuracy

A picosecond pulse detector implemented in 65-nm CMOS technology uses a three-stage injection-locked frequency divider to lock the output signal to the 9.6-GHz repetition rate, with an effective locking range of 142 MHz and a timing jitter of 0.29 psrms. The integrated system consumes 42 mW from a 1.3-V supply and occupies a total area of 0.9 mm², including on-chip antenna and pads.

Active/Passive Sensing for Detecting Vital Signs

Most conventional vital-sign sensing techniques are incompatible with the circuits in commercial wireless communication devices and do not readily provide both active and passive sensing. A novel active/passive dual-mode vital-sign sensing technique combines error vector magnitude (EVM) algorithms with wireless-communication demodulation to detect vital signs at distances up to 9m, even through a 15-cm-thick reinforced concrete wall.
