Initial version of real time model of acoustic transmission system with parametric multicarrier modulation

Abstract

Parametric multicarrier (PMC) modulation is a new concept which allows transmission system to use broad range of orthogonal subcarrier waveforms and adjust them on the fly. Two largest challenges in PMC systems are synchronization between receiver and transmitter and equalization. Although algorithms of these tasks for PMC systems have been already addressed multiple times, they have not been tested together in a full transmission system. In order to prove soundness of the proposed concepts and for assessing performance of the synchronization and channel estimation algorithms, a real-time model of acoustic transmission system using Simulink platform has been created. The purpose of this publication is to present design an test results of this model and outline advantages and drawbacks of the chosen approach. Paper contains general description of transmission system design, specific details of implementation and test results.
