This paper address the design of a front end for vehicular communications in the 5.9 GHz frequency band. The front end is being developed in accordance with the IEEE 8022.11p standard, which defines the physical layer for WLAN vehicular communications. Also presented are some simulations results, which demonstrate that 802.11p requirements are met. As the work is ongoing there are no practical results...
An Impulse based ultra-wide band (UWB) transceiver was designed using 130nm CMOS technology for a Bio-ranging system to improve the quality of cardiopulmonary resuscitation (CPR). It is developed to measure the depth of chest compression in CPR which is crucial factor for CPR quality using IR-UWB technology. The transmitter is composed of impulse generator and power amplifier (PA) operating at the...
In this paper, a Ka-band transmitter/receiver (T/R) front-end for a phased-array radar is proposed. The transceiver includes a receiver channel and a transmitter channel. A function link shared with the receiver channel and the transmitter channel is comprised of a 5-bit phase shifter and a variable gain amplifying circuit including an attenuator and a low noise amplifier. Connection to either the...
Attaching a tire pressure monitoring system (TPMS) on the inner liner of a tire allows sensing of important additional technical parameters, such as vehicle load or tire wearout. The maximum weight of the sensor is limited to 5 grams including package, power supply, and antenna. Robustness is required against extreme levels of acceleration. The node size is limited to about 1 cm3 to avoid high force-gradients...
This paper investigates the packet error rate (PER) performance enhancement through the antenna and the transceiver co-design for MB-OFDM UWB system. Five different UWB antennas, covering the whole UWB spectrum, are selected for study. Through the link-margin analysis and PER performance simulation, radio transceiver design specifications are optimized according to different antennaspsila performance...
