Method and device for generating aperiodic four-phase Z complementary sequence pair signal

Abstract

The invention belongs to the technical field of communication systems, and particularly relates to a method and a device for generating aperiodic four-phase Z complementary sequence pair signals in acommunication system. The method comprises the following steps: inputting a group of aperiodic binary Z complementary sequence pairs (a, b) with the zero correlation zone width of Z into a serial-parallel converter; correspondingly outputting each sequence element subjected to serial-parallel conversion to a symbol converter; the symbol converter processes the input sequence elements and outputs the sequence elements to the multiplying circuit; the multiplying circuit generates three paths of output; the adder performs staggered superposition on the three paths of output data of each sequenceelement in the sequence a and the three paths of output data of each sequence element in the sequence b to generate each sequence element of the non-periodic four-phase Z complementary sequence pair;performing parallel-serial conversion on each sequence element of the non-periodic four-phase Z complementary sequence pair by adopting a parallel-serial converter so as to output the non-periodic four-phase Z complementary sequence pair; the method can be applied to signal processing, communication systems, large-scale integrated circuit testing and the like.

Description

technical field [0001] The invention belongs to the technical field of communication systems, and relates to the field of generation of aperiodic four-phase Z-complementary sequence pairs; in particular, it relates to a method and device for generating aperiodic four-phase Z-complementary sequence pair signals in a communication system. Background technique [0002] The aperiodic Z-complementary sequence pair is composed of two sequences of the same length, and its characteristic is that the sum of the aperiodic autocorrelation functions of the two sequences has a zero correlation zone (ZCZ for short) near the origin of the time shift. In the ZCZ region, and have characteristics like impulse functions. In particular, when the ZCZ region contains all heterocorrelation functions, the non-periodic Z complementary sequence pair degenerates into a traditional non-periodic complementary sequence pair, also known as the Golay complementary sequence pair. The number of aperiodic Z ...
