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

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...

Zusammenfassung: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-parametric analog JSCC. Our results show that both, non-parametric and parametric, analog schemes outperform an ideal fully digital system based on scalar quantization, while the performance obtained with non parametric mappings is superior to that achieved with parametric systems.
