Experimental evaluation of analog joint source-channel coding in indoor environments

Abstract

Abstract-Recently, analog joint source-channel coding has been proposed as a means of achieving near-optimum performance for high data rates with a very low complexity. However, no experimental evaluation showing the practical feasibility of this scheme has been performed to date. In this paper, we describe a software-defined radio implementation of an analog joint source-channel coded wireless transmission system. Experimental evaluation carried out in an indoor environment making use of a wireless testbed shows that the performance perfectly matches that originally reported by simulations in Additive White Gaussian Noise (AWGN) channels for signal-to-noise ratio values below 20 dB
