由于中国电信CDMA网络发展到3G 之后，没有后续演进路线。所以中国电信 必然全力以赴建设基于FDD的NB-IoT 网络，不存在选择上的纠结， 力量用在一 处。5月17日， 中国电信宣布建成全球目前 覆盖最广的商用新一代物联网（NB-IoT） 网络， 实现31万个基站升级。 ...

The growing interest for high data rate wireless communications over the last few decades gave rise to the emergence of a number of wideband wireless systems. The resulting scarcity of frequency spectrum has been forcing wireless system designers to develop methods that will push the spectral effici ...

Since the telephone was invented in the late nineteenth century, there has been a steady development of telephone services, and the number of subscribers has con- tinuously increased. One of the most revolutionary developments in telephone serv- ice in the late twentieth century was the introduction ...

Wireless technology has been evolving at a breakneck speed. The total number of cell-phones in use (as of 2011) was over 6 billion for a 7 billion world population [1] constituting 87% of the world population. Additionally, with user convenience be- coming paramount, more and more functions are bein ...

OSCILLATORS are key building blocks in integrated transceivers. In wired and wireless communication terminals, the receiver front-end selects, amplifies and converts the desired high-frequency signal to baseband. At baseband the signal can then be converted into the digital domain for further data p ...

In order to improve the spectral efficiency in wireless communications, multiple antennas are employed at both transmitter and receiver sides, where the resulting system is referred to as the multiple-input multiple-output (MIMO) system. In MIMO systems, it is usually requiredto detect signals joint ...

At the macroscopic level of system layout, the most important issue is path loss. In the older mobile radio systems that are limited by receiver noise, path loss determines SNR and the maximum coverage area. In cellular systems, where the limiting factor is cochannel interference, path loss determin ...

In recent years, the research and developments in the area of RF and microwave technologies have progressed significantly due to the growing demand for applica- bility in wireless communication technologies. Starting from 1992, wireless com- munication technologies have become quite mature. In the m ...
