该程序实现了通信中16QAM的调制解调，并与理论误码率进行比较，证明仿真的正确性。(The program implements a 16QAM modulation and demodulation in a communication, with the theoretical bit error rate compared to prove the correctness of the simulation.)

In this paper, we study cost-sensitive semi-supervised learning where many of the training examples are unlabeled and different misclassification errors are associated with unequal costs. This scenario occurs in many real-world applications. For example, in some disease diagnosis, the cost of erroneously diagnosing a patient as healthy is much higher than that of diagnosing a healthy person as a patient. Also, the acquisition of labeled data requires medical diagnosis which is expensive, while the collection of unlabeled data such as basic health information is much cheaper

Matlab, Simulink, and a Communications Example

The problem-solving process for a computational problem can be outlined as follows: 1. Define the problem. 2. Create a mathematical model. 3. Develop a computational method for solving the problem. 4. Implement the computational method. 5. Test and assess the solution.

VTC file is the file format of the Brainvoyager. The FMRI matchine scan human s brain and get the vtc data. This toolbox can help you to read the vtc file into matlab.
