This paper presents the concept and demonstration of harmonic diversity for wireless communication, which makes use of multiple harmonic radio frequency (RF) channels with respect to the carrier frequency. Rather than frequency and space diversities widely used today to improve multipath fading, signal quality and spectral efficiency, the proposed scheme does not require multiple RF transceiver front-ends...
This paper presents a novel 90 GHz band RF transceiver using polarization-division duplex (PDD) technology. A PDD architecture is used for full-duplex communication in the single band. The RF transceiver can deliver 6 Gbps through six channels with a bandwidth of 3 GHz. The channel bandwidth is 500 MHz. A IF combining structure is used for multi-channel. To implement the system, a fourth-harmonically...
Recent advances in silicon technology, mm-Wave integrated circuit/antenna/package design, and beam-forming techniques at 60GHz, together with the emergence of suitable wireless standards, have enabled consumer electronics products to support wireless transmission of multi-Gb/s data such as high-definition (HD) audio/video content. Further expansion into portable and mobile platforms will require lower...
This paper presents the integrated circuit design of an ultra-wideband (UWB) transceiver for a wireless endoscope that enables real-time diagnosis with high resolution images. The implemented UWB transceiver is a non-coherent transmit reference (TR) architecture with differential binary phase shift keying (DBPSK) modulation. All-digital pulse generator (PG) and merged radio frequency (RF) front end...
Modern wireless transceiver systems are often overdesigned to meet the requirements of low bit error rate values at high data rates under worst-case channel operating conditions (interference, noise, multi-path effects). This results in circuits being designed with ldquosufficientrdquo margins leading to lower efficiency and high power consumption. In this paper, we develop an adaptive power management...
