New Method for Constructing Polyphase ZCZ Sequence sets
Abstract: In this paper, we propose a new method for constructing polyphase ZCZ sequences. The proposed sequences are composed of polyphase perfect sequences and polyphase unitary matrices. By this method, we can obtain polyphase ZCZ sequences which are not known yet. For example, as compared with the conventional method, quadriphase ZCZ sequences with wide zero correlation zones can be obtaine...
متن کاملA Study of Asymmetric ZCZ Sequence Sets
The present paper proposes two methods for constructing new asymmetric ZCZ sequence sets. ZCZ sequence sets are used as spreading sequences for AS-CDMA systems. An asymmetric ZCZ sequence set is a type of ZCZ sequence set and consists of multiple sequence subsets. Compared with conventional ZCZ sequence sets, the most important property of the proposed asymmetric ZCZ sequence sets is that the c...
متن کاملQuasi-Optimal and Optimal Generalized Mutually Orthogonal ZCZ Sequence Sets Based on an Interleaving Technique
The present paper proposes methods for constructing quasi-optimal or optimal generalized mutually orthogonal zerocorrelation zone (GMO-ZCZ) sequence sets. Zero-correlation zone (ZCZ) sequence sets have been studied as spreading sequences for approximately synchronized code-division multiple-access (ASCDMA) systems. A mutually orthogonal ZCZ (MO-ZCZ) sequence set is composed of several small ZCZ...
متن کاملMutually orthogonal sets of ZCZ sequences - Electronics Letters
Introduction: In a synchronous CDMA system, orthogonal spreading sequences can be employed to eliminate multiple access interference. However, in a wireless channel, orthogonality among different users tends to diminish because of inter-path interference. To reduce the interference among users in a multipath environment or in an approximately synchronised CDMA [1] environment, the concept of ge...
متن کاملA Study on Three-phase ZCZ Sequence Sets
The present paper investigates the application of three-phase ZCZ sequence sets to AS-CDMA systems that use coded TPSK. First, we clarify possible three-phase ZCZ sequence sets and the features of these ZCZ sequence sets. Next, we clarify the structure of the periodic correlation function between sequences that belong to three-phase ZCZ sequence sets. Finally, we propose a method for constructi...
