IIR_digital_desigh

VC开发的一款可以通过Access的增删改查进行存取记录的笔记本(VC Deve Note ,Could Sava your technology_note)

说明：  用于iOS平台的 ping demo,对苹果原生代码的封装(use for iOS partform ping demo)

说明：  本源码实现遗传算法，用于RA准则下的多用户OFDM自适应资源分配(The source code implements genetic algorithm for multi-user OFDM adaptive resource allocation under RA criterion)

DL/T645-2007清晰文本版，可以CTRL+F(DL/T645-2007 clear text version, you can CTRL+ F)

说明：  STM32F4 SPI 4线驱动RA8875 彩屏方案(stm32f4 driver ra8875 TFT lcd display)

说明：  单频信号经过多径时变信道后，输出信号的包络随时间随机起伏，输出信号的频谱从冲激谱变成一个窄带频谱。径数位20，变化频率从0—2HZ随机均匀抽取。(Single-frequency signal through time-varying multipath channel, the output signal envelope random fluctuations over time, the output signal from the impulse of the spectrum into a narrow-band spectrum spectrum. Digital Drive 20, changes in frequency from 0-2HZ uniform random samples.)

说明：  仿真相干光通信系统，包含各种损伤和均衡算法(the model of coherent optical fiber channel)

modbus协议栈，供大家参考！ 供大家参考！(modbus connection protocol stack, for your reference! For your reference!)

CDMA 信道估计matlab程序 内有中文详细注释(CDMA channel estimation matlab program)

说明：  产生随机信号，采用4fsk调制方式通过一个水声信道，再采用非相干解调(Generate random signal, use 4FSK modulation to pass through an underwater acoustic channel, and then use incoherent demodulation)
