MODBUS RTU using Attiny44 from Atmel

使用Jakes所假设的模型，用来产生信道抽头延迟线模型中的抽头增益过程所需的多普勒频谱成形滤波器有多种实现方法。时域FIR滤波器是最常用的一种实现方法。(Assumed the use of Jakes model, used to generate the channel-tap-tap delay line model of the process gain the necessary Doppler spectrum shaping filter has a variety of implementations. Time domain FIR filter is an implementation of the most commonly used method.)
