A Gray-Code Type Bit Assignment Algorithm for Unitary Space-Time Constellations
Abstract— Many techniques for constructing unitary spacetime constellations have been proposed. To minimize bit-error rate (BER) in a wireless communication system, constellation...

Constellation labeling maps for low error floors
A constellation labeling map is the assignment of a bit pattern to each symbol in a signal-set constellation. In a system with bit-interleaved coded-modulation and iterative decod...

The expansion and mixing time of skip graphs with applications
We prove that with high probability a skip graph contains a 4-regular expander as a subgraph, and estimate the quality of the expansion via simulations. As a consequence skip grap...

Mapping for Iterative MMSE-SIC with Belief Propagation
Abstract— In Multiple-Input Multiple-Output (MIMO) wireless systems, since different signals are transmitted by different antennas simultaneously, interference occurs between the...
