Guass-noise.zip - 产生一个高斯白噪声 利用MATLAB自带的fir1函数产生一个低通滤波器,限制高斯白噪声的带宽,由此产生了视频噪声。 利用产生的视频噪声,分别代入噪声调幅干扰的时域表达式,并且进行100次的积累后求平均值,对其进行快速傅里叶变换后,由此画出噪声调幅干扰的频域波形。 重复上述步骤,分别代入噪声调频干扰与噪声调相干扰的时域表达式,分别画出其频域波形与时域波形。

LTE_TX_PDSCH.zip - The inherent robustness of OFDM against multipath effects makes it an excellent choice for situations where multiple transmitters are used simultaneously (to avoid shadowing effects) and a path difference to the receiver exists. One of the major disadvantages of an OFDM based system is the characteristic high crest factor of the time domain signal. In traditional RF based systems, this usually necessitates a transmitter with a high dynamic range and hence results in reduced power efficiency. In the proposed optical LED system, this disadvantage is turned to an advantage - the time domain OFDM signal is used to modulate (IM-DD) the optical source.
