Sequences and their properties have been studied widely in different research areas
because they have useful characteristics which are used in many applications. Correlation …

LoRa has established itself as one of the leading technologies within evolving low power
wide area networks. In the patented LoRa modulation, a linearly increasing basis chirp …

Active sensing is a growing research field with long-standing open problems, whose
applications range from CDMA communication systems, ultrasonic imaging or ranging …

Index Modulation (IM) concept is exploited to propose a novel uplink multiple access
technique called, IM–multiple access (IMMA). In IMMA, part of the transmitted block for each …

5G physical random access channel (PRACH) will use new preamble formats based on
short Zadoff-Chu (ZC) sequences to enable new use cases. These formats result however in …

In this paper, two types of multiple binary zero correlation zone (ZCZ) sequence sets are
constructed: 1. Each set is a binary (2 n+ 1 Z cz, 2 n, Z cz)-ZCZ sequence set, which is one of …

Non-orthogonal multiple access (NOMA) is an emerging technology for massive connectivity
in machine-type communications (MTC). In code-domain NOMA, non-orthogonal spreading …

For various quasisynchronous (QS) CDMA systems such as LAS-CDMA system which
emerged recently, in order to reduce or eliminate the multiple access interference and …

We investigate the theory of the finite Heisenberg-Weyl group in relation to the development
of adaptive radar and to the construction of spreading sequences and error-correcting codes …

The recently proposed loosely synchronized (LS) spreading code can in principle realize an
intracell-interference-free quasi-synchronous code-division multiple-access (QS-CDMA) …
