MATLAB code for learning purpose

where M is a model object (IDMODEL, IDPOLY, IDSS, IDFRD, or IDGREY). MAG is the magnitude of the response and PHASE is the phase (in degrees). W is the vector of frequencies for which the response is computed. These can be specified by [MAG,PHASE,W] = BODERESP(M,W). The frequency unit is angular frequency (rad/s or rad/M.TimeUnit). Only frequencies up to the Nyquist frequency are considered.

OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。本程序实现OFDM与QPSK技术的比较(This program realization technology and the OFDM QPSK technology)
