代码说明:

  Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers, one exactly 90 degrees out of phase with respect to the other, are used to transmit data over a given physical channel. One signal is called the I signal, and the other is called the Q signal. Because the orthogonal carriers occupy the same frequency band and differ by a 90 degree phase shift, each can be modulated independently, transmitted over the same frequency band, and separated by demodulation at the receiver. For a given available bandwidth, QAM enables data transmission at twice the rate of standard pulse amplitude modulation (PAM) without any degradation in the bit error ratio (BER).

  • MATLAB_Demystify
    本书是直接针对MATLAB初学者,目的也不是教专家使用 MATLAB去解决复杂问题,相反,本书是介绍给MATLAB新人,使他们进入数学计算世界。这里要介绍的是使用MATLAB去解决某些基本问题——绘函数的图形、解代数方程、计算积分和解微分方程,所以要本书的例子较简单,针对新手。如果你以前从没接触MATLAB,或者是在使用MATLAB有很多疑问,那么本书将帮助你学得一些基本技巧,使用它们你将能够掌握MATLAB。本书仅是掌握MATLAB的垫脚石。 (MATLAB This book is directly aimed at beginners, the purpose is not to teach experts use MATLAB to solve complex problems, the contrary, this book is to introduce newcomers to MATLAB to enable them to enter math in the world. Here we introduce is the use of MATLAB to solve some fundamental problems- painted graphics functions, solve algebraic equations, calculation of integral equation of reconciliation, so the book' s examples of relatively simple, for the novice. If you' ve never contacted MATLAB, or the use of MATLAB has a lot of questions, then this book will help you learn some basic skills to use them you will be able to master MATLAB. This book is only a stepping stone to master MATLAB.)

  • PSODV-HOP
    说明:  对比了dv-hop基本算法,和加入pso后得算法。由于结果是随机产生的,不能保证每次得结构都能提高,但大部分时候,比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)
