In this letter, the error performance of an ultra-wideband (UWB) system with a hybrid pulse amplitude and Position modulation (PAPM) scheme over indoor lognormal fading channels is analyzed. In the PAPM UWB system, input data is modulated onto both the pulse amplitudes and pulse Positions.

1) Write a function reverse(A) which takes a matrix A of arbitrary dimensions as input and returns a matrix B consisting of the columns of A in reverse order. Thus for example, if A = 1 2 3 then B = 3 2 1 4 5 6 6 5 4 7 8 9 9 8 7 Write a main program to call reverse(A) for the matrix A = magic(5). Print to the screen both A and reverse(A). 2) Write a program which accepts an input k from the keyboard, and which prints out the smallest fibonacci number that is at least as large as k. The program should also print out its Position in the fibonacci sequence. Here is a sample of input and output: Enter k>0: 100 144 is the smallest fibonacci number greater than or equal to 100. It is the 12th fibonacci number.

HZK16文件是按照GB 2312-80标准,也就是通常所说的国标码或区位码的标准排列的。国标码分为 94 个区(Section),每个区 94 个位(Position),所以也称为区位码。其中01~09 区为符号、数字区,16~87 区为汉字区。而 10~15 区、88~94 区是空白区域。 如何取得汉字的区位码呢?在计算机处理汉字和ASCII字符时,使每个ASCII字符占用1个字节,而一个汉字占用两个字节,其值称为汉字的内码。其中第一个字节的值为区号加上32(20H),第二个字节的值为位号加上32(20H)。为了与ASCII字符区别开,表示汉字的两个字节的最高位都是1,也就是两个字节的值都又加上了128(80H)。这样,通过汉字的内码,就可以计算出汉字的区位码。

The PMSM FOC is made of several C modules, compatible with the free-of-charge IAR EWARM KickStart edition toolchain version 4.42. It is used to quickly evaluate both the MCU and the available tools. In addition, when used together with the STM32F103xx motor control starter kit (STM3210B-MCKIT) and PM motor, a motor can be made to run in a very short time. It also eliminates the need for time-consuming development of FOC and speed regulation algorithms by providing ready-to-use functions that let the user concentrate on the application layer. Moreover, it is possible to get rid of any speed sensor thanks to the sensorless algorithm for rotor Position reconstruction.

非常好的优化算法的书,详细介绍了蚁群算法和粒子群算法以及相关的matlab工具箱,讲了理论和应用给出了工具箱的下载地址。 Swarm intelligence is an innovative computational way to solve hard problems. In particular, particle swarm optimization, also commonly known as PSO, mimics the behavior of a swarm of insects or a school of fish. If one of the particle discovers a good path to food the rest of the swarm will be able to follow instantly even if they are far away in the swarm. Swarm behavior is modeled by particles in multidimensional space that have two characteristics: a Position and a velocity. These particles wander around the hyperspace and remember the best Position that they have discovered. They communicate good Positions to each other and adjust their own Position and velocity based on these good Positions.
