Introduction Ultrahigh field parallel imaging at 7T has been proven to be a promising imaging modality for humans because it can provide high spatial and temporal resolution simultaneously [1-4]. However, one of technical challenges in implementing ultrahigh field parallel imaging is to design the required transceiver arrays, especially the large size arrays, for signal excitation and reception...

This paper proposes a broadband wireless transceiver which can be reconfigured to any type of cyclic-prefix (CP) -based communication systems, including orthogonal frequency-division multiplexing (OFDM), single-carrier cyclic-prefix (SCCP) system, multicarrier (MC) code-division multiple access (MC-CDMA), MC direct-sequence CDMA (MC-DS-CDMA), CP-based CDMA (CP-CDMA), and CP-based direct-sequenc...

The choice of the CMOS radio frequency (RF) transceiver architecture affects the design of the whole system and is thus a fundamental one. In order to make a good choice, several factors have to be considered, the most important ones being: performance, power consumption, die size, cost, integration level, and time-to-market. The minimum required performance is dictated by the IEEE802.15.4 stan...

27 Abstract— In this paper, simulation and analysis of phase noise distortion in radio frequency (RF) transceiver of Wireless Local Area Network (WLAN) bridge system are presented. It is focused on the oscillator in RF transmitter and RF receiver in the transceiver. The effect of phase noise on the constellation error of RF transmitter and the receiver sensitivity of RF receiver is analysed bas...

Integration of multi-mode multi-band transceivers on a single chip will enable low-cost millimeter-wave systems for next-generation automotive radar sensors.
