OFDM

按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(According to a given target analog low-pass filter (Butterworth or Chebyshev low-pass low-pass) to approximate the ideal analog low-pass filter, then through the bilinear transformation method to digitize the analog filters, digital filters has been .)

使用matlab实现OFDM系统功能并仿真验证其功能 (Use matlab to realize the OFDM system simulation)

libev-4.15源码 libev是Marc Lehmann用C写的高性能事件循环库。通过libev，可以灵活地把各种事件组织管理起来，如：时钟、io、信号等。libev在业界内也是广受好评，不少项目都采用它来做底层的事件循环。node.js也是其中之一(libev-4.15 source libev Marc Lehmann is written in C, a high-performance event loop library. By libev, the flexibility to manage the organization of various events, such as: clock, io, signals. libev is also widely acclaimed in the industry, many projects have adopted it as the underlying event loop. node.js is one of them)
