ALOHA协议的思想很简单，只要用户有数据要发送，就尽管让他们发送。当然，这样会产生冲突从而造成帧的破坏。但是，由于广播信道具有反馈性，因此发送方可以在发送数据的过程中进行冲突检测，将接收到的数据与缓冲区的数据进行比较，就可以知道数据帧是否遭到破坏。(ALOHA protocol s thought is very simple, as long as the user data to be sent, although let they send. There are, of course, such conflicts which cause the destruction of the frame. But, because the radio channel has feedback, so the sender can be tested to the conflict in the process of sending data, the received data comparison with data of the buffer, you can know whether data frame was damaged.)

DVB-T 2k模式定时估计Matlab仿真。重新修改了程序。包括DVB-T信号产生，瑞利多径信道衰减，高斯噪声加入。 定时估计的粗定时用极大似然法，细定时用分散导频。首先确定导频模式，再通过相邻导频相关确定定时偏差。此方法适用于瑞利多径信道，高斯信道，也适用于莱斯多径信道。 信道估计利用DVB-T导频，LS估计，导频位置的时间插值，非导频位置频率插值，非常有效。 该程序经过多次运行无误，不足之处在于变量使用不规范，注释简单，读程序很费劲哈。 其特点是均采用经典算法，简单有效为主，对初学者很有帮助滴。(DVB-T 2k signal, timing estimation, channel estimation)

正余弦信号的谱分析 数字信号处理方法的一个重要用途是在离散时间域中确定一个连续时间信号的频谱，通常称为频谱分析，(Cosine signals are digital signal processing method of spectrum analysis is an important use is in the discrete time domain to determine a continuous-time signal spectrum, commonly referred to as spectrum analysis,)
