Abstract

In this paper we present a Link-to-System (L2S) level interface solution able to deal with multistate wireless channels, like when techniques such Multiple Input Multiple Output (MIMO) antennas and Orthogonal Frequency Division Multiplexing (OFDM) are considered. A physical layer model towards Long Term Evolution (LTE) of 3rd. Generation Partnership Project (3GPP) was used for evaluation of Effective SNR Mapping (ESM)-based solutions, when we have been assuming several Modulation and Coding Schemes (MCSs) and wireless channel models. The numerical results showed that the use of Exponential ESM (EESM) is suitable to the next generation of Orthogonal Frequency Division Multiple Access (OFDMA) wireless systems.
