Chapter 4 described the design and selection of the short range communication air interfaces tailored to Personal Networks application. These air interfaces consist of a low data rate (LDR) FM-UWB system and a high data rate (HDR) MC-SS system. The present chapter focuses on the hardware and software design and implementation that was carried out to prove the aforementioned concepts and to assess...
A RF transmitter IC in 0.13 µm CMOS technology for FM-UWB applications operating in the 6.25 – 8.25 GHz band is presented. Output power is higher than −10 dBm, phase noise −107 dBc/Hz at 1 MHz offset. Power consumption at 1.1 V supply voltage is less than 4.6 mW with calibration PLL on, and 4 mW in open loop mode including the output amplifier. The VCO circuit is capable of providing phase noise performance...
Wireless personal area networks (WPANs) have gained interest in the last few years, and several air interfaces have been proposed to cover WPAN applications. A multicarrier spread spectrum (MC-SS) air interface specified to achieve 130 Mbps in typical WPAN channels is presented in this paper. It operates in the 5.2 GHz ISM band and achieves a spectral efficiency of 3.25 . Besides the robustness...
This paper presents an in-depth study of a UWB indoor radio channel between 1 and 9 GHz, which was used for the subsequent development of a new statistical UWB multipath channel model, focusing on short range indoor scenarios. The channel sounding process was carried out covering different indoor environments, such as laboratories, halls or corridors. A combination of new and traditional parameters...
