Simulation and Analysis of the OFDM Transceiver Based Commutation System
Journal of Engineering, 2020 As a result of the increase in wireless applications, this led to a spectrum problem, which was often a significant restriction. However, a wide bandwidth (more than two-thirds of the available) remains wasted due to inappropriate usage. As a consequence,

Modeling the Cyclic Bandwidth Problem in QUBO for Quantum Annealing
We consider a graph labeling problem, i.e., the cyclic bandwidth problem, and its formulation in QUBO, the input language for quantum computers based on quantum annealing. To this end, we first consider a constraint programming model based on table constraints and then we derive from this model the QUBO formulation and its penalty matrix.

A hybrid heuristic approach for traffic light synchronization based on the MAXBAND
Soft Computing Letters, 2019 This study addresses a high resolution model for the synchronization of traffic lights on transport networks. A hybrid heuristic algorithm optimizes the mixed integer linear model, referred as MAXBAND, seeking to achieve maximal bandwidth by setting ...

Low-Complexity Oversampled OTFS Receivers With Reduced Overhead
IEEE Open Journal of the Communications SocietyOrthogonal Time Frequency Space (OTFS) modulation enables reliable communication in fast time-varying, frequency-selective channels. It is a delay-Doppler (DD) domain modulation that models the information symbols and the channel in the DD domain.

Approach to blind synchronization parameters estimation for OFDM systems
Tongxin xuebao, 2005 A method for increasing the cyclic period of a cyclostationary signal was first proposed. Then based on it, a cyclostationarity-based, blind algorithm for estimating synchronization parameters in the OFDM system was presented.
