Description: 采用频率调制 为1000Ｈｚ的载波，在解调前把加性白高斯噪声加入到调制信号。当噪声功率和调制信号功率比为０.００１，０.０１，０.０５，０.１和０.３是进行解调并绘出调制信号-The use of frequency modulation for the 1000Hz carrier, in the demodulation before AWGN added to the modulation signal. When the noise power and modulation signal power ratio of 0.3 is 0.001,0.01,0.05,0.1 and demodulation and modulation signals mapped

Description: In this paper, the feasibility of replacing a chaos source by an equivalent digital pseudo-random generator realized using Linear Feedback Shift Register (LFSR) is studied. Particular emphasis is given on the digital implementation Piece-Wise Linear A ffine Maps (PWAM). As an application, an FPGA implementation of four different maps has been experimentally verifi ed in a FM-DCSK test radio system.

Description: 本调频收音机主要由FM/AM收音机芯片CXA1019、PLL且频率合成器BU2614和单片机AT98C51组成。收音机以单片机AT98C51为控制核心, 实现全频搜索、指定频率范围搜索和手动搜索电台 本收音机还使用了数字电位器(X9511)控制音量。采用液晶显示器显示载频和时钟等信息, 大幅度降低了系统的功耗。整机实现3V 电源工作, 采用E2PROM(AT24C04)存储电台, 还增加了立体声解码功能。-Mainly by the FM radio FM/AM radio IC CXA1019, PLL and frequency synthesizer BU2614 and SCM AT98C51 composition. AT98C51 microcontroller for the control of the radio to the core, to achieve full frequency search, specify the frequency range of search and manual search radio station the radio also uses a digital potentiometer (X9511) to control the volume. Carrier frequency with LCD display and clock and other information, significantly reducing system power consumption. Machine to achieve 3V supply, the use of E2PROM (AT24C04) storage station, also increased the stereo decoding.
