Errors in multilevel flash memories and multilevel optical systems are asymmetric in nature because of the underlying device physics. These errors can be modeled using the m-ary asymmetric channel. In this work, a general m(  ≥ 2)-ary Asymmetric Varshamov (AV) channel for these systems is introduced. Also, a Divesting Combining Type-I Hybrid ARQ protocol using t-Asymmetric Error Correcting/All Asymmetric Error Detecting (t-AEC/AAED) codes is presented and its throughput performance is studied.
