Physical Abstraction Method (RBIR) for OFDM System

Abstract

Now a day’s Computer simulations are often used to predict the performance of cellular networks. Link level stimulations involve in varying channel conditions and ambiguity. In order to predict the accurate performance of cellular network, a system level simulator, which includes the performance of the link between each base and mobile station, should be used, but this is computationally prohibitive. So to reduce the complexity caused by the system level simulator, “The Abstraction from the link level simulations” can be used. Thus, the objective of the physical layer abstraction is to accurately predict the link layer performance in a computationally easy way. This is accurate, computationally simple, also relatively independent of channel models and extensible to interference models and multi antenna processing. In this papers a Link quality model, Received Bit Information Rate (RBIR) is used in system evaluations to simplify the simulation complexity.
