卷积码的编码和VB译码
在MATLAB上设计一个(2,1,3)卷积编码器和对应的采用维特比译码算法的译码器。编码器的生成多项式为:[1 0 1;1 1 1]。将编码器的输出经过一个高斯白噪声信道的结果作为译码器的输入,观察比较译码器输出和编码器输入,了解卷积码的容错性,并计算译码结果的误比特率.(A convolutional coder (2, 1, 3) and corresponding decoder using Vitby decoding algorithm are designed on MATLAB. The generating polynomial of encoder is: [1 01; 11 1]. The output of the encoder through a Gauss white noise channel as a result of the decoder input, compare the output of the decoder and encoder input, understand the fault tolerance of convolutional code, and calculate the decoding results of bit error rate.)

serial to parallel
直接序列扩频通信中采用QPSK调制时,须将产生的串行数据首先串并变换成两路,本程序就是实现这种串并变换!(Direct sequence spread spectrum communications using QPSK modulation, it is necessary to have a string of serial data and converted into the first two, the process is to realize such a string, and transform!)

DWellsThesis
This thesis presents simulation data on array operation in wideband communication systems.
It is shown that array structures with closer inter-element spacing outperform structures with
much larger inter-element spacing. It is also shown that circular structures outperform linear
structures. This performance dierence between the classications of arrays is due largely
to the circular array s ability to handle high levels of interference. Even though a diversity
combining scheme (MRC) was used in the simulator, the arrays provided interference rejection
capabilities due to the closely spaced antenna elements.
