The Application of EESM and MI-Based Link Quality Models for Rate Compatible LDPC Codes

System evaluation of different resource allocation, power control and Link Adaptation (LA) solutions require the multi-cell system simulations, which provide important reference to the standardization and system design. Such a system-level simulator is expected to be reliable and quick enough, which requires a very accurate and simple link quality model. The Exponential Effective-SNR Mapping (EESM) model and Mutual Information-based (MI-based) model were proposed recently, which have been proved to be pretty accurate and independent of fading for 3GPP Turbo-coded Orthogonal Frequency Division Multiplexing (OFDM) system.
