With 26 entirely new and 5 extensively revised chapters out of the total of 39, the Mobile
Communications Handbook, Third Edition presents an in-depth and up-to-date overview of …

We construct new sequences over finite rings having optimal Hamming correlation
properties. These sequences are useful in frequency hopping multiple-access (FHMA) …

In this paper we construct new classes of optimal frequency-hopping sequences (FHSs) with
respect to the Lempel-Greenberger bound and the Peng-Fan bound by interleaving …

The paper presents families of quadriphase sequences derived from maximal length
sequences over\bf Z _4 having good correlation properties. These are:(i) families of …

Compressed sensing (CS) is a new method of data acquisition which aims at recovering
higher dimensional sparse vectors from considerably smaller linear measurements. One of …

Pseudo-noise sequences (PN sequences), also referred to as pseudo-random sequences,
are sequences that are deterministically generated but possess some favorable properties …

A bound on exponential sums over Galois rings is used to construct a nested chain of Z/sub
4/-linear binary codes and binary sequences. When compared with the chain of Delsarte …

Global Navigation Satellite Systems (GNSSs) typically use low-correlation sequences that
have length related to the common clock frequency of 10.23 MHz. In particular, operations in …

This paper gives new families of quadriphase sequences obtained from large linear
complexity sequences over Z 4 by making use of generalized permutation monomials over …

We determine the exact values of the linear complexity of 2p-periodic quaternary sequences
over Z_4 (the residue class ring modulo 4) defined from the generalized cyclotomic classes …
