—This paper presents two polynomial-complexity techniques for assigning Gray-like binary labels to arbitrary Grassmannian constellations. In the first technique, the constellati...

For a single transmit and receive antenna system, a new constellation design is proposed to combat errors in the phase estimate of the channel coefficient. The proposed constellati...
Network coding is an effective method to improving relay efficiency by reducing the number of transmissions. However, its performance is limited by several factors such as packet l...
We recently showed that arbitrarily reliable communication is possible within a single coherence interval in Rayleigh flat fading as the symbol-duration of the coherence interval ...

Abstract: In field studies designed to uncover opportunities for computationallyintensive business applications, we observed an interaction pattern we term "constellations&quo...
Abstract— The Active Constellation Extension (ACE) technique is a lossless (in terms of throughput) Peak-to-Average Power Ratio (PAR) reduction technique that adaptively extends ...
Abstract—The high peak-to-average-power ratio (PAR) of Orthogonal Frequency Division Multiplexing (OFDM) transmission systems significantly reduces the power efficiency or perf...
