Regardless of the branch of science or engineering, theoreticians have always been enamored with the notion of expressing their results in the form of closed-form expressions. Quite often, the elegance of the closed-form solution is overshadowed by the complexity of its form and the difficulty in evaluating it numerically. In such instances, one becomes motivated to search instead for a solution that is simple in form and simple to evaluate.

The field of digital communication has evolved rapidly in the past few decades, with commercial applications proliferating in wireline communi- cation networks (e.g., digital subscriber loop, cable, fiber optics), wireless communication (e.g., cell phones and wireless local area networks), and stor- age media (e.g., compact discs, hard drives). The typical undergraduate and graduate student is drawn to the field because of these applications, but is often intimidated by the mathematical background necessary to understand communication theory.

This books attempts to provide an extensive overview on Long-Term Evolution (LTE) networks. Understanding LTE and its Performance is purposely written to appeal to a broad audience and to be of value to anyone who is interested in 3GPP LTE or wireless broadband networks more generally. The aim of this book is to offer comprehensive coverage of current state-of-the-art theoretical and techno- logical aspects of broadband mobile and wireless networks focusing on LTE. The presentation starts from basic principles and proceeds smoothly to most advanced topics. Provided schemes are developed and oriented in the context of very actual closed standards, the 3 GPPP LTE.

Public telephone operators and new independent wireless operators through- out the world are deploying wireless access in an effort to drastically reduce delivery costs in the most expensive part of the network?the local loop. Available radio technology enables both existing and new entrants to access subscribers in a rapid manner and deliver their basic telephony products and broadband-enhanced services.

PLL(Phase Locked Loop)： 為鎖相回路或鎖相環(huán)，用來統(tǒng)一整合時(shí)鐘信號(hào)，使高頻器件正常工作，如內(nèi)存的存取資料等。PLL用于振蕩器中的反饋技術(shù)。 許多電子設(shè)備要正常工作，通常需要外部的輸入信號(hào)與內(nèi)部的振蕩信號(hào)同步。一般的晶振由于工藝與成本原因，做不到很高的頻率，而在需要高頻應(yīng)用時(shí)，由相應(yīng)的器件VCO，實(shí)現(xiàn)轉(zhuǎn)成高頻，但并不穩(wěn)定，故利用鎖相環(huán)路就可以實(shí)現(xiàn)穩(wěn)定且高頻的時(shí)鐘信號(hào)。

Wherever possible the overall technique used for this series will be "definition by example" withgeneric formulae included for use in other applications. To make stability analysis easy we will usemore than one tool from our toolbox with data sheet information, tricks, rules-of-thumb, SPICESimulation, and real-world testing all accelerating our design of stable operational amplifier (op amp)circuits. These tools are specifically targeted at voltage feedback op amps with unity-gain bandwidths<20 MHz, although many of the techniques are applicable to any voltage feedback op amp. 20 MHz ischosen because as we increase to higher bandwidth circuits there are other major factors in closing theloop: such as parasitic capacitances on PCBs, parasitic inductances in capacitors, parasitic inductancesand capacitances in resistors, etc. Most of the rules-of-thumb and techniques were developed not justfrom theory but from the actual building of real-world circuits with op amps <20 MHz.
