ADSL
- ADSL （Asymmetric Digital Subscriber Line ，非对称数字用户环路）是一种新的数据传输方式。它因为上行和下行带宽不对称，因此称为非对称数字用户-ADSL (Asymmetric Digital Subscriber Line Asymmetric Digital Subscriber Loop) is a new way of data transmission. It uplink and downlink bandwidth asymmetry, know
OFDM_Channel-estimation
- OFDM(正交频率调制)实现多载波调制基本思想是将带宽信道分解成许多并行的窄子信道，是每个子信道的想干带宽，从而实现平稳衰落。搭建了完整的OFDM信道链路系统，运用三种不同的信道估计方法(LS信道估计、DFT信道估计、Improved-DFT信道估计)，并对AWGN理想信道和衰落信道误码情况进行了仿真和比较。-OFDM (Orthogonal Frequency Modulation) multicarrier modulation basic idea bandwidth channel is

ssft_D_n2_Aeff
- 光孤子matlab仿真 注意程序里面的脉冲定义，morder=1就是高斯脉冲，高于1就是超高斯形状。 高斯脉冲的时候，Nc这个参数表征的是啁啾给脉冲带宽带来的增加， 比如Nc=2表示由于啁啾使得高斯脉冲的带宽变为没有啁啾时候的两倍，以此类推。 超高斯脉冲的时候这个参数没有相应的意义。-Soliton matlab simulation Note program inside the pulse defined morder = 1 is the Gaussian pul

Amplitude Modulation (Baseband, Passband)
- A key consequence of the usual double-sideband amplitude modulation (AM) is that the range of frequencies the signal spans (its spectral bandwidth) is doubled. Thus, the RF bandwidth of a signal (measured from the lowest frequency as opposed to 0 Hz)
