ACHIEVO OH Ñ ONELE MONTED IN THE FFT TRANSFORMER

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is based on space-time block coding MIMO_OFDM communication system simulation design. This system includes the QPSK modem, IFFT modulation, space-time coding and decoding, symbol-based channel estimation training and other communication module.)

说明：  实现了DCT的算法，用Matlab实现了任意维图像的DCT变换问题。(DCT algorithm implemented using Matlab implementation of arbitrary-dimensional DCT-image problems.)

matlab noaa海洋数据 分析各个海区的温度 用matlab做任意经纬度不同深度的切片 例子是东海PN断面(The various sea temperature matlab noaa ocean data analysis using matlab do any different latitude and longitude depth slices examples PN section in the East China Sea)

full wave rectifierDuring the period from 伪 to 蟺, the input voltage vs input current is are positive and the power flows from supply to the load. The converter is said to be operated at rectification mode .During the period from 蟺 to 蟺+伪 , the input voltage vs is negative and the input current is is positive and reverse power flows from load to the supply. The converter is said to be operated in inversion mode. Depending on the value of 伪, average output voltage can be either positive or negative and hence provides 2 quadrant operation.

说明：  卡尔曼滤波器是用前一个估计值和最近一个观察数据估计信号的值，他是用状态方程和递推的方法进行估计，本例用来追踪一个5阶的FIR不确定的滤波器系数。(Kalman filter is to use the previous estimate and the most recent observation data to estimate the value of the signal, he is using the state equation and recursive estimation methods, in this case is used to track a 5-order FIR filter coefficients of uncertainty.)
