自适应滤波程序 (Adaptive filtering procedure)

本程序对两种固定步长和一种变步长最小均方误差算法的权值收敛进行了仿真，结果表明变步长的算法效果更优。(This programme compare LMS algorithm with VSLMS algorithm. The result indicate that the latter is better.)

a simple method of pca. how to find mean and to normalize data

depso clustering algorithm written in matlab

Differential PSK (DPSK) 􀂄 Inexpensive 􀂄 Quadrature Phase Shift Keying (QPSK) 􀂄 Twice as spectrally efficient than BPSK 􀂄 Offset QPSK (OQPSK) 􀂄 reduce envelope variation 􀂄 π/4 QPSK 􀂄 reduces envelope variations to a lesser extent than OQPSK can be noncoherently detected

possion image reconstruction

仿真采用Erlang B模型，此仿真考虑用户呼叫时，若无空闲信道则被阻塞的情况。对话务量和阻塞率进行仿真(Simulation using Erlang B model, consider the user calls this simulation, the channel was idle without congestion. Blocking rate for traffic simulation )
