常见的插值函数是interp1,可以在MATLAB中help interp1中学习一下。下面给出的MATLAB代码也是使用的interp1这个插值函数。 除了上面基于导频的估计方法,其实ODFM还有基于判决反馈的信道估计方法、基于DFT的信道估计、基于叠加信号的信道估计、盲信道估计等等方法,在《MIMO-OFDM无线通信技术及MATLAB实现》中均有介绍。 基于D...

Because many functions in MATLAB® automatically run on a GPU if you supply a gpuArray data argument, you can accelerate the simulation simply by generating the information bits as a gpuArray. A gpuArray object represents an array stored in the GPU memory. In this simulation, the gpuArray ...
The invention discloses a comb spectrum code division multiple access and OFDM combined system and a modulation method and a demodulation method thereof. A comb spectrum code division multiple access system and an orthogonal frequency division multiplex system (OFDM) in the system perform corresponding...
