Description: 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.

Description: OFDM的英文全称为Orthogonal Frequency Division Multiplexing，中文含义为正交频分复用技术。这种技术是HPA联盟（HomePlug Powerline Alliance）工业规范的基础，它采用一种不连续的多音调技术，将被称为载波的不同频率中的大量信号合并成单一的信号，从而完成信号传送。由于这种技术具有在杂波干扰下传送信号的能力，因此常常会被利用在容易外界干扰或者抵抗外界干扰能力较差的传输介质中。-OFDM The English called Orthogonal Frequency Division Multiplexing, Chinese meaning is orthogonal frequency division multiplexing. This technique is the basis of HPA Alliance (HomePlug Powerline Alliance) industry standard, which uses a discrete multi-tone technique, a different carrier frequency will be referred to the large number of signals into a single signal, thereby completing the signal transmission. Because of this technology has the ability to transmit signals at clutter, so often can be exploited in an easily resist outside interference or poor outside interference in the transmission medium.

Description: High Peak to Average Power Ratio (PAPR) is a critical issue in multicarrier communication systems using Orthogonal Frequency Division Multiplexing (OFDM), as in the Second Generation Terrestrial Digital Video Broadcasting (DVB-T2) system. This
problem can result in large performance degradation due to the nonlinearity of the High Power Amplifier (HPA) or in its low
power efficiency.

Description: method based on Neural
Network (NN) technique and accompanied with MMSE
(Minimum Mean Square Error), which corrects at the receiver
level, the Non-Linear (NL) distortions due to the HPA (High
Power Amplifier).-In this paper, we present a method based on Neural
Network (NN) technique and accompanied with MMSE
(Minimum Mean Square Error), which corrects at the receiver
level, the Non-Linear (NL) distortions due to the HPA (High
Power Amplifier). The neural network consists on a feedforward
Multi-Layer Perceptron (MLP) associated with
Levenberg-Marquardt learning algorithm. The results show
that the neural network compensator brings perceptible in a
complete VBLAST MIMO OFDM (Vertical Bell Laboratories
Layered Space-Time Multiple-Input Multiple-Output
Orthogonal Frequency Division Multiplexing) system running
under a Rayleigh fading channel.
