  2. ESM should not be correlated with channel types • Pre-defined tables for different channels is not a viable solution because in a lot of scenarios, there is no pre-defined channels, i.e., beamformed channels, OFDMA. • RBIR methods shown little correlation with channels [1-7] • ESM Accuracy • PER v.s. effective SNR curves for different channels and bandwidths show that RBIR method is pretty accurate [1-7] • Packet length can be derived from one typical packet length • Modeling of practical (channel estimation etc.) loss will be discussed in the future • Implementation complexity • Modulation dependent look-up tables require minimal additional complexity • Complexities of all frequency domain processing ESM methods are similar PHY Abstractions Jianhan Liu, etc. Mediatek Inc.
