Range Extension for UWB Communications
نویسندگان
چکیده
UWB shows great promise for use in a number of wireless communications applications, in particular, short range high bit rate networking. However, due to the emissions limits set by the FCC, commercial systems are limited in range for high data rates. To achieve greater range, both simple and advanced techniques need to be investigated. Current designs for UWB (at least those in the open literature) focus on a small number of modulation and pulse shaping schemes. As such, simple improvements should be investigated first to increase system range, such as better modulation schemes, channel coding, and/or Rake receivers. More sophisticated designs should then be investigated. In this white paper we investigate the use of different modulation and coding schemes on the Range of UWB, as well as a simple analysis of the Rake receiver. Additionally, due to the potentially large number of Rake fingers that may be needed, we discuss the need for low power Rake designs. Finally, we propose areas of research in UWB for communications.

A Novel Small E–Ring Shaped Monopole Antenna with Dual Band-Notch Function for UWB Wireless Communications
This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...

On February 14, 2002, the Federal Communications Commission (FCC) of the United States adopted the First Report and Order that permitted the commercial operation of ultra wideband (UWB) technology (FCC, 2002). The FCC allocated a bandwidth of 7.5GHz, i.e. from 3.1GHz to 10.6GHz, to unlicensed use for UWB applications. Ultra Wideband is defined as any communication technology that occupies great...
