摘要/Abstract

摘要：

为了增加多载波码分多址通信系统的容量，构造了一类具有组内互补特性的序列集合。该序列集合可以分成多个序列组，每个序列组内部的序列具有理想的相关性能，同时序列组之间具有不同宽度的零互相关区。作为传统互补序列集合的扩展，所构造的组内互补序列集合中的每一个序列组都是一个完备互补序列集合，从而既可以满足容纳大数量用户的需求，也可以保证系统的抗干扰性能。

关键词: 多载波码分多址, 互补序列, 交织迭代, 相关性能

Abstract:

For increasing the capacity of multi-carrier code division multiple access communication systems,a class of sequences with intra-group complementary properties was constructed.The constructed sequence set could be divided into multiple sequence groups.The correlation properties of sequences from the same sequence group were ideal while the correlation functions between sequences from different sequence groups possessed zero cross-correlation zones with different widths.As an expansion of traditional complementary sequence sets,each sequence group of the designed intra-group complementary sequence set becomes a complete complementary sequence set,which can satisfy the requirements to accommodate a large number of users and also can ensure the anti-interference properties of systems.

Key words: multi-carrier code division multiple access, complementary sequence, interleaving iteration, correlation properties
