Near Shannon limit performance of low density parity check codes - Electronics Letters

This is the situation of interest in a trunked mobile system with priority, as the application of priorities is under heavy traffic: if the system is correctly sized, under regular load conditions no priorities are needed, as the waiting time must be low for all customers. For all delay probabilities the relative error of the mean waiting time for priority calls is no longer guaranteed to be lower than lo%, but the overestimation is still better than the waiting time calculated by considering the MIMIC queue and only eqn. 1.
