Abstract

An accurate and simple link quality model is crucial in system evaluation of different link adaptation (LA) solutions, for it acts as a link-to-system (L2S) interface which provides the block-error rate (BLER) performance of a certain modulation coding scheme (MCS) corresponding to the current SINR states. Our previous work in [1] has verified the good accuracy of the MI-based model for rate compatible LDPC coded OFDM system. In this paper, adaptive modulation and coding (AMC) strategy and two hybrid ARQ schemes of variable retransmission length, partial chase combining and full incremental redundancy, have been designed to check the accuracy of the look-up tables (LUTs) obtained by the MI-based model. The predicted results are quite in accord with the simulation ones, which confirms that the MI-based model provides accurate and simple LUTs for LA design of LDPC codes.
