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.)

矩量法是求解电磁场边界值问题中一种行之有效的数值方法.它所做的工作是将积分方程化为差分方程,或将积分方程中积分化为有限求和,从而建立代数方程组,故它的主要工作量是用计算机求解代数方程组.所以,在矩量法求解代数方程组过程中,矩阵规模的大小涉及到占用内存的多少,在很大程度上影响了计算的速度.如何尽可能的减少矩阵存储量,成为加速矩量法计算的关键.此处介绍了方法(MoM is the solution of electromagnetic field boundary value problem in an effective numerical method. It is the work done by integral equations into differential equations, or integral equations into a finite sum of points, so as to establish algebraic equations Therefore, it is the main workload of the computer to solve algebraic equations. Therefore, in the moment method for solving algebraic equations, the matrix size relates to the amount of memory, to a large extent affected the speed of calculation. how to maximize the reduction of matrix storage has become accelerated MoM calculation of the key. introduce the method here)
