Title
Link-Level Abstraction Of Ieee 802.11ay Based On Quasi-Deterministic Channel Model From Measurements
Abstract
In this paper, we analyze the performance of link-level abstraction for orthogonal frequency-division multiplexing (OFDM) and single-carrier (SC) modes in IEEE 802.11ay wireless systems over the 60 GHz millimeter-wave band. In particular, we evaluate the effectiveness of the three existing effective signal-to-noise ratio (SNR) metric (ESM) schemes (i.e., exponential ESM (EESM), mean mutual information per coded bit (MMIB) and post-processing ESM (PPESM)). Furthermore, to deal with the issue that EESM calibration is dominated by channel realizations with poor error performance, we introduce a classification based EESM (CEESM) scheme with a new metric named coefficient of variation, which is used to measure the severity of frequency-selective fading. Finally, we present several important insights developed through extensive experimentation. Based on our validation results, the MMIB and PPESM can be employed with minimum computational complexity for OFDM and SC modes, respectively. In contrast, EESM and CEESM can be considered for both modes with better accuracy, but at a cost of high implementation complexity.
