METHOD AND APPARATUS FOR COLLISION RESOLUTION IN A DELAY-CRITICAL RADIO TELECOMMUNICATIONS SYSTEM

摘要

In a PRACH channel, colliding signals are resolved by use of a number o f training-like symbols in the colliding data payloads. The signals are estimated by spatio temporal filters running a training-based or semi-blind algorithm, and a selection criterion is applied to the estimated signals, such as distance from the finite alphabet or the mean square error.
