Non-parametric analog Joint Source Channel Coding for amplify-and-forward two-hop networks

Eduardo Alves Hodgson, Glauber Gomes de Oliveira Brante, Richard D. Souza, Javier Garcia-Frías

ICASSP 2017accepted

We investigate the use of discrete-time analog joint source channel coding (JSCC) in an amplify-and-forward two-hop wireless network subject to Rayleigh fading channels. The discrete-time analog source is compressed using either 2:1, 3:1 or 4:1 low delay dimension-compression parametric and non-para…

Parametric analog mappings for correlated Gaussian sources over AWGN channels

Pedro Suárez-Casal, Óscar Fresnedo, Luis Castedo, Javier Garcia-Frías

ICASSP 2016accepted

We address the transmission of bivariate Gaussian sources using analog Joint Source Channel Coding (JSCC). The analog mappings are specifically designed to exploit the correlation between the source symbols. A parametric mapping based on sinusoidal functions is proposed and its performance is compar…
