Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. High Peak-to-Average Power Ratio (PAPR), which leads to power inefficiency in the RF portion of the transmitter, is a major drawback of OFDM.

这是我自己收藏的两个源代码程序，比较有用，希望对大家有所帮助(This is my own collection of two source code procedures, more useful, I hope all of you to help)

This paper presents the simulation of a simple First Order plus Delay Time (FOPDT) process model using advanced control algorithms. Specifically, these advanced algorithms are the IMC-based PID controller, the Model Predictive Controller (MPC) and the Proportional-Integral-Plus Controller (PIP) and their performance is compared with the conventional Proportional – Integral – Derivative (PID) algorithm. The simulations took place using the Matlab/Simulink™ software.
