本文叙述一种二进制数据传输技术,其中每个二进制符号选为在1/2F的时间时隔内以指定方式相重叠的n个(Sin2πFt)/2πFt型式的脉冲。这种重叠对于二进制输入会产生两个以上的接收电平,但其所得则是容许实现Nyguist速率(在带宽F中每秒2F个符号)。重叠系数的适当选择将改变频谱的分布以适合于特殊的应用。定义了系统函数最感兴趣的种类,叙述了与之相关联的编码程序,并概述了其性能特征。
This article describes a binary data transmission technique in which each binary symbol is selected as n (Sin2πFt) / 2πFt-type pulses that overlap in a specified manner over a 1 / 2F time interval. This overlap produces more than two receive levels for binary inputs, but the result is a Nyguist rate (2F symbols per second in bandwidth F) is allowed. The proper choice of overlap coefficients will change the distribution of the spectrum to suit the particular application. Defined the most interesting types of system functions, describes the associated coding procedures, and outlines its performance characteristics.
