qam
一、 本程序采用16QAM调制方式,对一串2进制信源进行调制,用升余弦滚降函数进行基带调制,再调到高频信道;在信道上加入高斯白噪声,运用匹配滤波器解调,画出解调星座图,运用最小欧氏距离译码判决,计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)

kalman
Overview
The Simulink model shows an example how the Kalman Filter can be
implemented in Simulink. The model itself is configured with a Gaussian
process connected with a Kalman Filter. To directly use this model, one
only needs to provide model prarameters including parameters of the
Gaussian process, which are state space matrices, A, B, C, and D, initial
state, x0, and covariance matrices, Q and R and similar parameters for
the Kalman Filter, which can be in different values to mimic the model
mismatch, plus the state covariance, P. The following examples show how
this model can be used.
The Kalman Filter can also be used as a standard model block to be
connected with any other systems
