Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.

The objective of this project is to investigate the possibility of applying a dynamic channel allocation to cMCN. The proposed method is a multihop dynamic channel assignment (MDCA) scheme that works by assigning channels based on interference information in the surrounding cells. A channel searching strategy, sequential channel searching (SCS) is developed for the MDCA scheme. This strategy is responsible for the channel updation which includes channel assignment for a new request and channel release after the completion of the communication process. Through computer simulation, we show that the proposed MDCA scheme using the SCS strategy improves the system capacity significantly.

PID调节器结构简单、参数易于调整，当被控对象精确数学模型难以建立、系统的参数又经常发生变化时，应用PID控制技术，在线整定最为方便。 (PID adjustor simple structure, easy adjustable parameters, when the controlled object mathematical model is hard to build up, the parameters of the system and often changes, application of PID control technology, online setting the most convenient.)
