摘要

结果表明,具有规定的频谱特性的二值序列可以通过基于增量调制算法的优化程序来设计。该方法特别适用于长度为128,256和512位的低通序列的设计,经过简单的积分处理,显示出与2型非递归数字滤波器脉冲响应相关的频谱特性。高通序列可以通过一个简单的变换得到。讨论了该方法的局限性和量化误差的含义。得到了实现给定频谱带宽所需的最小序列长度的理论预测。应用包括数字滤波器,它可以通过执行基本算术运算的数字硬件简单地实现。

Design and application of binary sequences with optimised lowpass properties
It is shown that binary sequences having prescribed spectral properties may be designed by an optimisation procedure based on a delta-modulation algorithm. The method is specifically applied to the design of lowpass sequences of lengths 128,256 and 512 bits which, after a simple integration process, exhibit spectral properties related to type-2 nonrecursive-digital-filter impulse responses. Highpass sequences can be obtained by a simple transformation. The limitations of the procedure and the implications of quantisation error are discussed. A theoretical prediction is obtained for the smallest sequence length necessary to achieve a given spectral bandwidth. Applications include digital filters, which can be simply implemented by digital hardware performing primitive arithmetic operations.
