现代通信系统仿真中锁相环仿真的PLL前处理程序(Modern communication systems simulation of the PLL phase-locked loop simulation procedures before)

OFDM高功率放大器.供学习matlab的同学交流学习 (The Matlab code investigates the harmful effects of high power amplifier on ofdm signals. It is imagined that the amplifier destroy the amplitude of the transmitted signal due to saturation and has no effect on the signal phase. The model is acceptable for solid state amplifier to some extend.)

A generalized Richardson extrapolation routine that can perform multiple extrapolation steps, can accommodate arbitrary leading error terms, can handle any uniform refinement scheme (e.g. h/2, h/3, h/5, etc), and can report a full extrapolation table including comparing against a known good solution. Able to handle vector inputs. Compatible both with MATLAB and Octave. Includes Octave-style unit tests.

说明：  本程序主要是实现最优多用户检测，从而能够实现最优的误码率性能和最好的抗远近效应能力。(Multi-user Dectection )
