N2 - The capacity region of a Multiple Access Channel can be increased by feedback to the sources, since feedback enables cooperative transmission. Focusing on a linear cellular system (as for a highway or a corridor), a novel transmission strategy is proposed that exploits feedback from the neighboring mobile stations (MSs). The strategy enables cooperative communications via "analog network coding" (i.e., broadcasting and interference cancellation via side information) to exchange signalling information among MSs. Numerical results show that the proposed technique provides gains over non-cooperative strategies in the low-signal-to-noise-ratio regime.
