VCSOA_opticalswitch
这是一个关于基于VCSOA的光开关的仿真程序。仿真程序基于传输矩阵法设计的，将整个器件在轴向按折射率的不同分成很多层。计算了在外部抽运（即泵浦，加在放大器上的工作电流）呈现周期性变化时，放大器将输出一系列的光脉冲，即光开关。
(
This is a simulation package for computing the characteristics of the VCSOA when acting as an optical switch, which is designed based on TMM( transfer matrix method). The whole device is splitted into many segments in the axis direction according to different index. When the external pump is a periodic signal, the output of the VCSOA would be a pulse train, which can be used as optical switch. )

ofdm_without_noise
Technology that offers full vehicular speed mobility and that can readily coexist with HSPA and earlier networks. OFDM/OFDMA technology is introduced for the LTE downlink, supporting very high data rates of up to 300Mbps while Single-Carrier FDMA (SC-FDMA) is used in the uplink with data rates of 80Mbps possible. Additionally, LTE supports operation both in paired and unpaired spectrum (FDD and TDD) using channel bandwidths of approximately 1.4MHz up to 20MHz. The frequency domain scheduling can be done in OFDMA. One of the main challenges in OFDMA is the high peak-to-average radio of the transmitted signal, which requires linearity in the transmitter. The linear amplifiers have low efficiency therefore, OFDMA is not an optimized solution for a mobile uplink where the
