Query: Multilevel Code Construction for Compound Fading Channels   We consider explicit constructions of multi-level lattice codes that
universally approach the capacity of the compound block-fading channel.
Specifically, building on algebraic partitions of lattices, we show how to
construct codes with negligible probability of error for any channel
realization and normalized log-density approaching the Poltyrev limit. Capacity
analyses and numerical results on the achievable rates for each partition level
are provided. The proposed codes have several enjoyable properties such as
constructiveness and good decoding complexity, as compared to random one-level
codes. Numerical results for finite-dimensional multi-level lattices based on
polar codes are exhibited.
