LTE has a distributed system architecture optimized for IP connectivity. Circuit switched technology is not supported by LTE at all; therefore it provides VoIP based voice service only. In LTE, VoIP packets are carried with significant protocol overhead, thus transporting each voice packet separately is a waste of bandwidth. A possible way to improve the bandwidth efficiency of voice service over...
We consider shock measures in a class of conserving stochastic particle systems on ℤ. These shock measures have a product structure with a step-like density profile and include a second class particle at the shock position. We show for the asymmetric simple exclusion process, for the exponential bricklayers’ process, and for a generalized zero range process, that under certain conditions these shocks,...
