Abstract:
This paper focuses on the effect that various co-transmission schemes have on a single receiver's SNR, under a stochastic-geometry setting for the emitters' location. The model includes all standard effects of ground propagation: power law to account for the distance, fast fading, shadowing, plus delay spread (resolvable multipath). The schemes addressed include: the dimension-expanding fully orthogonal case (namely channel-blind transmission on completely orthogonal dimensions); the two extreme co-transmission schemes of fully coherent (perfectly known channel) as well as fully incoherent (purely channel-blind) cases; randomly orthogonalized co-transmission; plus selected transmission schemes such as the strongest signal or the nearest node to the receiver. The emphasis is on outage statistics, but capacity and bit-error-rate are also computed in selective cases. The analysis highlights the role of the various parameters involved, in particular demonstrating the importance of resolvable multipath on the relative performance of the schemes addressed.
