C-Progrmming-Language(second)
本书是由c语言的设计者brian w. kernighan和dennis m. ritchie编写的一部介绍标准c语言及其程序设计方法的权威性经典著作。全面、系统地讲述了c语言的各个特性及程序设计的基本方法，包括基本概念、类型和表达式、控制流、函数与程序结构、指针与数组、结构、输入与输出、unix系统接口、标准库等内容。
本书的讲述深入浅出，配合典型例证，通俗易懂，实用性强，适合作为大专院校计算机专业或非计算机专业的c语言教材，也可以作为从事计算机相关软硬件开发的技术人员的参考书。 在计算机发展的历史上，没有哪一种程序设计语言像c语言这样应用如此广泛(C language book is written by the designers of brian w. kernighan and dennis m. ritchie write a description of the standard c language and the authority of the program design classic. Comprehensive and systematic about the c language of all the basic features and programming methods, including basic concepts, types and expressions, control flow, function and program structure, pointers and arrays, structures, input and output, unix system interface, the standard library and so on.
Book about simple terms, with a typical example, user-friendly, practical, suitable as a computer professional or computer professional colleges of the c language materials can also be as engaged in computer-related hardware and software technology developed by staff reference. In the history of computer development, no programming language such as c language so widely used)

Resource Allocation in WPCN
说明： The possible solution to overcome network performance issue is to maximize the weighted sum rate (WSR) and to minimize the total power consumption. To solve this we consider this problem as maximization or minimization problem for which we utilize global optimization techniques. We can incorporate different optimization approaches to form hybridized techniques which assist in minimizing the power consumption and maximizing the weighted sum rate.

（一）基本任务：单频正弦波模拟信号的简单数字化。即对一个单频正弦波模拟信号进行抽样、均匀量化、PCM二进制自然编码。
1、主要步骤和要求：
（1）单频正弦波模拟信号的抽样实现。要求输入信号的幅度A、频率F和相位P可变；要求仿真时间从0到2/F，抽样频率为Fs=20F；要求给出抽样信号samp的波形图。
（2）单频正弦波模拟信号均匀量化的实现。要求对抽样信号sampl归一化后再进行均匀量化；要求量化电平数D可变；要求输出信号为平顶正弦波；要求给出量化输出信号quant的波形图，并与抽样信号samp画在同一图形窗口中进行波形比较。
（3）单频正弦波模拟信号PCM二进制自然编码的实现。要求按量化序号给出PCM二进制自然编码；要求给出编码后的数字序列pcm。
