　研究了基于滤波器组的单载波频域均衡技术的基本原理和实现方法,通过系统对比基于滤波器组的方法与基于FFT方法的异同之处,从其产生的机理上阐明了基于滤波器组的单载波频域均衡技术能够克服FFT 方式的主要缺点的原因(Of filter-based single-carrier frequency domain equalization technology, the basic principle and method, through the system, filter-based approach compared with the FFT method based on the similarities and differences between, from production to clarify the mechanism of the filter-based single-carrier frequency domain equalization techniques to overcome the main drawback of FFT method because)

一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算， 而将所有参数全部用整数，运算到最后再除以一个2的N次方数据（相当于移位），作类似定点数运算，可 大大提高运算速度，根据控制精度的不同要求，当精度要求很高时，注意保留移位引起的“余数”，做好余 数补偿。这个程序只是一般常用pid算法的基本架构，没有包含输入输出处理部分。 (A typical PID process, using the microcontroller as a control cpu, make some simplification, the specific PID parameters must be determined experimentally by a specific object. As the chip processing speed and ram resource constraints, generally do not use floating-point operations, and all parameters of all integers, and divided by an operator to the last N-th power of 2 data (the equivalent of the shift) for a similar fixed-point operations, can greatly improve the speed of operation, according to the different requirements of precision control, when high precision, attention to retain the shift caused by the " remainder" and on the remainder of compensation. This procedure is commonly used basic structure pid algorithm, does not include input and output processing section.)
