2fsk
2FSK是利用数字基带信号控制在波的频率来传送信息。经过调制后的2FSK数字信号通过两个频率不同的带通滤波器f1、f2滤出不需要的信号，然后再将这两种经过滤波的信号分别通过包络检波器检波，最后将两种信号同时输入到抽样判决器同时外加抽样脉冲，最后解调出来的信号就是调制前的输入信号。(gudi hduidf hdag sdd w)

Anadaptivefilteringapproachtotargettracking
A method is presented for augmenting an extended
Kalman filter with an adaptive element. The resulting estimator
provides robustness to parameter uncertainty and unmodeled
dynamics.(A method is presented for augmenting an ext Kalman ended with an adaptive filter element. T he resulting estimator provides robustness to parameter uncertainty and unmodeled dynamics .)

FDM
正交频分复用（OFDM）是一种特殊的多载波传输技术。它可以有效地对抗多径衰落，能够以很高的频谱利用率来实现高速数据传输。分析介绍了OFDM系统的基本原理及系统性能，以Matlab为开发平台，仿真了OFDM系统的误码率，仿真结果表明OFDM系统在较低信噪比下也具有较好的性能(Orthogonal Frequency-division Multiplexing（OFDM） is a special kind of multi-cartier transmission technology. It can effectively overcome multi-path fading and increase the spectral usage efficiency to implement high-speed data transmission. This paper analyzes the basic principle of OFDM system and system performance, and simulates the Bit Error Rate （BER） of OFDM system on the platform of Matlab. The simulation results show that the OFDM has a good performance.[)

说明： 载波侦听多路访问。采用分布式控制方法，附接总线的各个结点通过竞争的方式，获得总线的使用权。只有获得使用权的结点才可以向总线发送信息帧，该信息帧将被附接总线的所有结点感知(Carrier Sense Multiple Access. A distributed control method, each attached to the bus node on a competitive basis, to obtain the right to use the bus. Only with the right to use the node can send messages to the bus frame, the message frame will be attached to all nodes sense the bus)

Wiener
设计一维纳滤波器
(1)产生三组观测数据：首先根据s(n)=a s(n-1)+w(n)产生信号s(n)，将其加噪（信噪比分别为20dB,10 dB，6 dB），得到观测数据x1(n), x2(n), x31(n).
(2)估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L,N对实验结果的影响。

(2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss the impact changing L, N of the experimental results.)
