Implementation of an OTFS-DCP-Based Communication System on Software-Defined Radios
Year: 2025
Type: conference-paper
Abstract: In this manuscript, the problem of implementing, on commercial software defined radios, a digital communication system that employs the Orthogonal Time Frequency Space (OTFS) modulation is addressed. Few available manuscripts discuss this issue and they all overlook the use of cyclic prefixesin both the time and frequency domains (i.e., the use of a double cyclic prefix), a crucial aspect to achieve robustness to doubly-selective fading channels. In this paper, we describe the implementation of the OTFS-based communication system developed in [1] on a couple of software defined radios by National Instruments. Various technical information about the signal processing algorithms employed at the transmit and receive sides is provided. Experimental results evidence that the proposed communication system is able to reliably operate in the presence of strong Doppler affecting the communication channel
