Kaya, O. (2006). Window and backwards decoding achieve the same sum rate for the fading cooperative gaussian multiple access channel. Paper presented at the IEEE Globecom 2006, 1-5. doi:10.1109/GLOCOM.2006.65Özet
For a two user fading Gaussian multiple access channel with user cooperation, we show that window decoding achieves the same sum rate as backwards decoding, when the encoding is done using block Markov superposition coding. We prove this result by showing that when optimum power control is employed, the additional constraints on the sum rate imposed by the use of window decoding instead of backwards decoding are never active. While doing so, we also provide some properties of power allocation that is jointly optimal with block Markov coding and window decoding.

Channel adaptive encoding and decoding strategies and rate regions for the three user cooperative multiple access channel
Edemen, Çağatay; Kaya, Onur (IEEE, 2008)For a cooperative Gaussian multiple access channel (MAC), we propose a new channel adaptive three user cooperation strategy, based on a non-trivial extension of block Markov super-position encoding. We obtain the expressions ...
