书籍 Time-Varying Channels
Wireless communications has become a field of enormous scientific and economic interest. Recent
success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless
local area networks (WiFi/IEEE 802.11x), wireless broadband access (WiMAX/IEEE 802.16x), and
digital broad ...
书籍 UMTS+Performance+Measurement+A+Practical+Guide
Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor
UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding
the data captured on the links and analysing how the different data segments and messages
are related to each other. In general ...
技术资料 Multisim建模高手编制的国产电子管模型库
Multisim仿真软件对于构思与设计电子线路非常方便，现在已经升级到Version12，但我个人还是用习惯了Version10，也比较稳定。不过这个软件的破解版元件模型库非常有限，特别是电子管模型，基本都是外国型号，国产的几乎没有。下面我借花敬佛，提供一个Multisim建模高手编制的国产电子管模型库给同好们下载。 ...
