In this paper, the impact of clipping noise on optical wireless communication (OWC) systems employing orthogonal frequency division multiplexing (OFDM) is investigated. The two existing optical OFDM (O-OFDM) transmission schemes, asymmetrically clipped optical OFDM (ACO-OFDM) and directcurrent- biased optical OFDM (DCO-OFDM), are studied. Time domain signal clipping generally results from direct current (DC) biasing and/or from physical limitations of the transmitter front-end.

AM调制，simulink仿真，适用于通信系统仿真课程(AM modulation simulink simulation, applicable to the communications system simulation programs)

This code is used for patch test of plain strain in FEM.

An orifice, through which hydraulic fluid flows, has a specially shaped inlet and exit in an attempt to minimize losses. During tests the measured variations of mass flow rate q with pressure drop (p1-p2) across the orifice yield the data shown below. (a) From these data estimate the orifice loss coefficient c0 (b)plot the flow v.s. pressure drop curve with the estimated c0 to validate your estimation.

本程序是mazen.O的经典论文：Performance Analysis of two-hop ralayed transmissions over rayleigh fading channels 的文章中所附的仿真图的程序，跑出的结果和文章中的附图是一样的！可以跑出里面的三张图，包括瑞利衰落下中继信道的中断概率的蒙特卡洛及公式的仿真，及选择不同的增益的性能差别曲线！ (This program is mazen.O classic paper: Performance Analysis of two-hop ralayed transmissions over rayleigh fading channels in the article accompanying the simulation of the processes, results and articles ran in the figures are the same! You can run out of the inside of the three figures, including the Monte Carlo simulation and the formula for the outage probability of Rayleigh fading relay channel, and select a different gain performance difference curves!)
