对于学习DSP重要的是理清外设的工作构架,相应的寄存器如何设置,没有必要对寄存器花太多的时间去研究,用的时候能找到(寄存器的名称都是英文的缩写,很好理解的)。学习DSP,先找本中文教材入个门,之后你会发现好多地方、尤其是真正要用的,往往也是最复杂的地方书上都找不到,更谈不上做什么项目了,这时候就要开始深入研究Data Sheet,以及官网的源代码示例,有了之前的中文教材基础看起来就快多了;

MIMO-OFDM is a key technology for next-generation cellular communications (3GPP-LTE, Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n), wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB). This book provides a comprehensive introduction to the basic theory and practice of wireless channel modeling, OFDM, and MIMO, with MATLAB ? programs to simulate the underlying techniques on MIMO-OFDMsystems.Thisbookisprimarilydesignedforengineersandresearcherswhoare interested in learning various MIMO-OFDM techniques and applying them to wireless communications.

Since the advent of optical communications, a great technological effort has been devoted to the exploitation of the huge bandwidth of optical fibers. Start- ing from a few Mb/s single channel systems, a fast and constant technological development has led to the actual 10 Gb/s per channel dense wavelength di- vision multiplexing (DWDM) systems, with dozens of channels on a single fiber. Transmitters and receivers are now ready for 40 Gb/s, whereas hundreds of channels can be simultaneously amplified by optical amplifiers.

Thepredecessorvolumeofthisbookwaspublishedin1996.Intheyears since then, some things have changed and some have not. Two of the things that have not changed are the desire for better models and faster simulations. I performed the original simulations on my “hyperfast” 133-MHz computer! At the time, I thought if I could just getafastercomputer,allofourSPICEproblemswouldbehistory,right? TodayIamsimulatingonacomputerthathasa2.6-GHzprocessorwith 512 MB of RAM, and I would still say that simulations run too slow. The computer technology has evolved, but so have the models. In 1996 wewereperformingsimulationson100-kHzpowerconverters,whereas today I routinely see 1- and 2-MHz power converters.

使用片式磁珠和片式电感的原因:是使用片式磁珠还是片式电感主;要还在于应用。在谐振电路中需要使用片式电感。而需要消除不需要的EMI噪声时,使用片式磁珠是最佳的选择。 磁珠是用来吸收超高频信号,象-一些RF电路,PLL,振荡电路,含超高频存储器电路(DDRSDRAM,RAMBUS等)都需要在电源输入部分加磁珠。而电感是一种蓄能元件,用在LC振荡电路,中低频的滤波电路等,其应用频率范围很少超过错50MHZ。 磁珠专用于抑制信号线、电源线上的高频噪声和尖峰干扰,还具有吸收静电脉冲的能力。磁珠的功能主要是消除存在于传输线结构(PCB电路)中的RF噪声,RF能量是叠加在直流传输电平上的交流正弦波成分,直流成分是需要的有用信号,而射频RF能量却是无用的电磁干扰沿着线路传输和辐射(EMI)。要消除这些不需要的信号能量,使用片式磁珠扮演高频电阻的角色(衰减器),该器件允许直流信号通过,而滤除交流信号。通常高频信号为30MHz以上,然而,低频信号也会受到片式磁珠的影响
