This is book about bluetooth programming and other items. Is good for beginerss.

支持Telnet功能的Modem通讯程序 (Modem commnunication supports telnet)

Nist Conceptual model for smart grid communication.

说明：  ofdm的编码过程，用evm和比特率进行对比(The encoding process of OFDM is compared with EVM and bit rate)

说明：  关于VC编写的一份串口通讯程序，测试已通过(VC prepared on a serial communication program, test has passed)

实现基于STBC的MIMO_OFDM通信系统在不同信噪比情况下接收端的误比特率的仿真。发射端包括基于基带调制、空时编码、导频插入、IFFT、串并合并以及添加循环前缀；接收端包括去除循环前缀、取出导频估计信道、FFT运算以及并串合并，空时解码等。仿真中采用QPSK、空时编码采用4*3的复正交空时编码矩阵。OFDM子载波数为100，每个子载波传输66个符号，每个符号2比特。IFFT长度为512个符号。发射天线为3个接收天线为2个。(The BER simulation of MIMO_OFDM communication system based on STBC under different SNR is realized. The transmitter includes baseband modulation, space-time coding, pilot insertion, IFFT, serial-parallel combination and adding cyclic prefix; the receiver includes removing cyclic prefix, extracting pilot estimation channel, FFT operation, parallel-serial combination, space-time decoding, etc. The complex orthogonal space-time coding matrix is used in QPSK and space time coding in 4*3. The number of OFDM subcarriers is 100, and each subcarrier transfers 66 symbols with 2 bits per symbol. IFFT is 512 symbols in length. The transmitting antenna is 3 receiving antennas, 2.)

实现了64qam，16qam和QPSK的误码率仿真(The bit error rate simulation of 64qam, 16QAM and QPSK is realized.)

在CBuilder中如何控制游戏手柄，对手柄编程(How to control the game in the CBuilder handle, to handle programming)

其中包含了OFDM系统的简单仿真，有SLM算法输入输出的比较，PAPR明显降低(Which contains a simple simulation of the OFDM system, the comparison of the input and output of SLM algorithm, PAPR is significantly reduced)

基于ARM的嵌入式程序设计.rar,对arm的学习会有很大的帮助。(ARM-based embedded programming. Rar, on the arm of the study will be of great help.)
