Channel Measurement and Analysis for the 60 GHz Radio in a Reflective Environment
نویسنده
چکیده
Wideband channel measurements at the 60 GHz frequency band in a reflective environment with different antenna heights are presented. The log-distance model of the normalized received power (NRP) is used to fit the measured data for both line-of-sight (LOS) and non-line-of-sight (NLOS) cases. Also, the impact of the biconical antennas and the reflective environment on the channel properties is analyzed and explained. Results show that the most favorable NRP values are found in the case that the Tx and Rx antennas are at the same height. Also, in most cases, the scatter paths have more contributions on the total received power than the direct path. In addition, in the LOS case, the NRPs become less dependent on the Tx-Rx separation owing to the combined effect of the antenna and the reflective environment. The analysis of these results can be instructive for the deployment of a 60 GHz system in a reflective environment.

Wireless channel measurement results for 60 GHz within a closed metal cabinet are provided. A metal cabinet is chosen to emulate the environment within a mechatronic system, which have metal enclosures in general. A frequency domain sounding technique is used to measure the wireless channel for different volumes of the metal enclosure, considering both lineof-sight (LOS) and non-line-of-sight (...
متن کاملEffect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...

Research in inexpensive millimeter wave devices and electronically steerable antennas forbodes future high speed communications that use carrier frequencies at millimeterwave frequencies such as 38 and 60 GHz. At these frequencies, the available RF bandwidth is much greater than that of current 4G systems, resulting in massive amounts of data rates, and high gain millimeterwave steerable antenn...

This work presents an 11 GS/s 1.1 GHz bandwidth interleaved ∆Σ DAC in 65 nm CMOS for the 60-GHz radio baseband. The high sample rate is achieved by using a two-channel interleaved MASH 1-1 architecture with a 4-bit output resulting in a predominantly digital DAC with only fifteen analog current cells. Two-channel interleaving allows the use of a single clock for the logic and the multiplexing w...
