Description: pathChirp is an active probing tool for estimating the available bandwidth on a communication network path. Based on the concept of "self-induced congestion," pathChirp features an exponential flight pattern of probes we call a chirp. Packet chirps offer several significant advantages over current probing schemes based on packet pairs or packet trains. By rapidly increasing the probing rate within each chirp, pathChirp obtains a rich set of information from which to dynamically estimate the available bandwidth.

Description: 在3.49-3.51GHZ频段内的典型中国城市环境下，地面信号衰落仍服从经典的指数对数分布。在中度误差（σx =10.291）下，路损指数在3.1-3.7之间。半径2公里的小区内，RMS时延在3-4微秒之间；典型的办公室环境中，存在直达径时RMS时延小于0.1微秒。在城市环境中，多径现象很明显，主要由高层建筑物引起，并以簇的方式存在。在城市中低速移动条件下（接收机移动速度小于100 Km/h）某一强径的生存时间通常超过10分钟，但相对到达时间会发生滑动。单一小区内的传播环境具有一定相关性，如果存在直达径，相关性会上升到0.4-0.5。此外，室外室内的测量结果都可以证明Jake模型关于入射角分布假设的合理性。当天线间距在1个载波波长增大到10个载波波长时，天线相关性在0.05-0.4之间。
SIMO信道探测系统能够揭示B3G信道的很多特征，但不能够全面、充分的分析和评估B3G信道。在后续工作中，我们将进一步改进这个测试系统，对B3G系统作更深入的研究。
参考-Aided by a 1-Tx and 2-Rx system working in 3.5GHz frequency and 20MHz bandwidth, JSI-MTLab studied the classic B3G urban wireless propagation environment of China and the classic indoor channel propagation environment through a recent indoor and outdoor wireless propagation measurement. A new path loss exponent is proposed in such band while the general outdoor model of path loss is verified. Also, the statistic results of RMS excess delay, max excess delay and mean excess delay in both indoor and outdoor scenarios are given. The lag-time domain and time-frequency domain channel responses are analyzed. At the end, the results of correlation of different propagation environment in the singular cell and antenna correlation are given as well as the phenomenon being analyzed and explained.
