Verdú's seminal work offers an elegant characterization of capacity per unit cost, but many results hold only when a cost-free input symbol is available. Furthermore, optimal transmission strategies under such scenarios typically result in infinitesimal spectral efficiency. We argue that the existence of a cost-free symbol is unrealistic and that the resulting low-rate transmission policies are not...
Satisficing game theory offers an alternative to classical game theory that describes a flexible model of players' social interactions. Players' utility functions depend on other players' attitudes rather than simply their actions. However, satisficing players with conflicting attitudes may enact dysfunctional behaviors, which results in poor performance. We present an evolutionary method by which...
We investigate the use of multi-user detection to improve performance in MIMO interference networks. Unfortunately, while multi-user detection often allows higher data rates, it greatly complicates the problem: in addition to choosing a transmit covariance for each transmitter, we must decide which signals each receiver will detect and which data rates make such detection feasible. We discuss methods...
