Application of Nega-cyclic Matrices to Generate Spreading Sequences
نویسندگان
چکیده
In the paper, we present a new class of orthogonal bipolar spreading sequences designed based on Goethals-Seidel construction with negacyclic matrices. The sequences can be designed for any length equal to 4 (mod 8), and possess good correlation properties. In particular, their aperiodic autocorrelation characteristics are very good. That can be traded off for improvement in the crosscorrelation performance using a diagonal modification method, as shown in the example.

On the construction of n-dimensional designs from 2-dimensional designs
design, then = (f(hI + h2 + ... + hn») is a proper n-dimensional design. A difficulty with this construction that it can applied to small number of (2dimensional) designs. This paper develm)s a very general technique for generating a proper n -dimensional design from 2-dimensional designs. Indeed, it is shown that Drake's generalised Hadamard matrices, Berman's nega-cyclic and (i)-cyclic (gener...
متن کاملNonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...
متن کاملStudy of spread codes with block spread OFDM
This paper presents the study undertaken with block spread OFDM and compares three spreading matrices. The matrices include the Hadamard, Rotated Hadamard and Mutually Orthogonal Complementary Sets of Sequences (MOCSS). The study is carried out for block lengths of M = 2, M = 4 and M = 8 and it shows that all the spreading matrices show improvement and a better performance over the conventional...

متن کاملA New Document Embedding Method for News Classification
Abstract- Text classification is one of the main tasks of natural language processing (NLP). In this task, documents are classified into pre-defined categories. There is lots of news spreading on the web. A text classifier can categorize news automatically and this facilitates and accelerates access to the news. The first step in text classification is to represent documents in a suitable way t...
