word文档对球形译码的理论原理和仿真code

说明：  实现了一个直接扩频系统，使用BPSK作为调制解调方法。并比较白噪声AWGN及瑞利衰落(rayleigh fading)环境下，误码率的影响。(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray >>semilogy([1:8],BER_awgn(1:8), g* ) hold on semilogy([1:8],BER_ray(1:8), -.b* ) hold on grid on )

无线手机使用的集成式功放器/淤波器前端The use of wireless mobile devices, integrated power amplifier / silt-wave front-end(The use of wireless mobile devices, integrated power amplifier/silt-wave front-end)

说明：  用于通信方向中的信道估计，使用的语言是matlab(Used for channel estimation in the communication direction, the language used is matlab)

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.)

说明：  最基础的检测概率；虚警概率；漏检概率与门限的关系。(Energy detection;Single threshold.)

利用3GPP交织器和LTE交织器完成turbo码的仿真并做比较，不同解码算法的比较(Using 3GPP Interleaver and complete LTE interleaver turbo code simulation and comparison, a comparison of different decoding algorithms)

说明：  基于matlab实现OFDM，调制方式为QPSK，可以对信道的状态进行估计(OFDM is realized based on MATLAB, the modulation mode is QPSK, and the channel state can be estimated)
