35GHz宽带信道测量和相关参数分析

借助于35?GHz频段、20?MHz带宽的一发双收系统，对中国典型的后3代(B3G)城市信道环境和典型的室内信道环境进行了测量和研究；在该频段验证了室外小区的通用路径损耗模型，提出了适用于中国环境的大尺度衰落模型，为中国后3代信道建模和系统设计提供了参考. 通过对室内外信道时延扩展、时延时间域信道响应、时频域信道响应，以及室外信道传播环境相关性和天线相关性的测量、统计及分析，为后3代系统的评估提供了重要的参数指标.

3.5GHz Broadband Channel Measurement and Parameter Analysis

Based on the 1Tx and 2Rx systems working in 35?GHz frequency and 20?MHz bandwidth, the typical beyond 3G (B3G) urban wireless propagation environment of China as well as typical indoor channel propagation environment was studied through a recent indoor and outdoor wireless propagation measurement. The general outdoor model of path loss was verified. A new largescale fading mode was proposed, which provided reference model for China B3G channel modeling and system design. Important criteria for B3G system evaluation were provided by the measurement, analysis and statistic results of several parameters, namely 1) r.m.s excess delay and max excess delay in both indoor and outdoor scenarios, 2) the lagtime domain and timefrequency domain channel responses, 3) the correlation between different propagation environment in the singular cell, and the antenna correlation.
