Publication number: 20240183935Abstract: Aspects presented herein may enable a wireless device (e.g., a joint FMCW radar and communication system) to transmit and/or receive an FMCW signal and an OFDM signal using the same time and frequency resources. In one aspect, a first wireless device receives an indication of a scheduled transmission for an FMCW waveform via a set of time-frequency resources. The first wireless device transmits or receives the FMCW waveform via the set of time-frequency resources based on the indication, where the FMCW waveform is separated from an OFDM waveform by a buffer zone including a first gap in frequency, where the first gap in frequency is based on an interference level between the FMCW waveform and the OFDM waveform.Type: ApplicationFiled: December 5, 2022Publication date: June 6, 2024Inventors: Danlu ZHANG, Weimin DUAN, Jing JIANG, Roberto RIMINI, John Edward SMEE, Peter Pui Lok ANG, Lai Kan LEUNG, Seyedkianoush HOSSEINI

Patent number: 10782339Abstract: Automatic test equipment with multiple components to generate highly accurate and stable analog test signals and method for operating the test system in semiconductor manufacturing process are disclosed. Output analog signals from existing test systems often fail the stability and accuracy requirement with less than 10 mV variations for testing certain electronic devices, due in part to environmental condition variations such as temperature fluctuations. Traditional compensation mechanisms for temperature variations involve time consuming and disruptive calibration procedures. Disclosed here is a system and method that provides near real-time monitoring and compensation for temperature-induced variations via a digital control mechanism that compensates for environmental variations in a time scale of less than 10 milliseconds and maintains the AC output analog signal with 10 milliVolt accuracy.Type: GrantFiled: April 29, 2016Date of Patent: September 22, 2020Assignee: Teradyne, Inc.Inventors: Zai-man Chen, Pei-Lai Zhang
