Description: This a GUI based system. The GUI is invoked from the command line by typing "ui_start". The GUI is self explanatory.
Tool tips are given in blue color. The cursor needs to be positioned on these for detailed explanation. The main file is
"runsim.m".It is recommended that 10000 runs (packets) be used for plotting frame error rates and 5000 runs for BER/SER.
Obviously, you would require a fast machine!!! At least a P4 machine.
We have used trace criterion for 4PSK states 4,8 and 16 as an example for 2x2 cases. The reader can use rank and determinant
criteria, by commenting the trace criterion lines and copying the rank and determinant lines from the respective 2x1 cases.
The SNR range can be varied by correcting the range at line 36 of file "runsim.m".
This software has been tested with MATLAB version 6.0 and above with signal processing and communications toolbox options.

Description: 训练错误率和交叉验证错误率相等，在样本比较大时，这个结果是可以预期的；训练错误率一般低于测试错误率，但是当样本数据比较少时，实验也出现了意外，样本多的那组测试错误率比样本少的训练错误率还要小；在本实验中，同组数据的交叉验证错误率比独立测试错误率高，这个反常现象是因为样本的原因所致，交叉验证的样本小，而独立测试时所用训练样本数目大，因而出现这种情况。分类线上，fisher准则是一条直线，而贝叶斯分类器实际上是一个类似椭圆的封闭曲线；很明显，贝叶斯分类器比fisher分类器要好。-Training error rate and cross- validation error rates are equal, the larger the sample , this result is to be expected training error rate is generally lower than the test error rate , but when comparing the sample data came from the experiment there was an accident, that more samples group test error rate less than the training sample error rate is smaller In this experiment, the same set of data cross-validation error rate than independent test error rate, this anomaly is because the sample of reasons , cross-validation sample is small,And independent testing large number of training samples used , resulting in this situation.Classification online , fisher criterion is a straight line , while the Bayesian classifier is actually a closed curve similar to elliptical It is clear that the Bayesian classifier is better than the fisher classifier .

At the same time the height and weight data as the characteristic, with Fisher identification method for linear classifier, and the application of the classifier to training and test sample, investigation and test training error condition. Will the training sample and utility of decision on the drawing boundary paint, and at the same time before the Bayes method with optimal classifier also paint chart, the result of the comparison of the similarities and differences. 3. Select the above or before any a kind of method of experiment, with a method for training set in the estimation error rates, and on the test set get error rates are compared.

Description: Research towards meeting the higher demands for
higher data rates was the main reason for the birth of an
evolution technology towards the 4th generation mobile
communication systems. This evolution to the current 3rd
generation UMTS systems was given the name E-UTRA/UTRAN
Long Term Evolution (LTE) by the 3GPP. This paper analyzes
the requirements for this evolution and evaluates the
performance of the OFDM-LTE system under different
propagation impairments (AWGN and multipath fading
channels involving Pedestrian and Vehicular scenarios) in terms
of bit and symbol error rates (BER and SER) for different
modulation formats.
