Base station coordination has received much attention as a means to reduce the inter-cell interference in cellular networks. However, this interference reducing ability comes at the expense of increased feedback, backhaul load and computational complexity. The degree of coordination is therefore limited in practice. In this paper we explore the trade-off between capacity and feedback load in a cellular...
Wireless spectrum is a regulated resource, whose control and usage is regulated by government agencies. The allocation of spectrum to interested parties is usually conducted through auctions, and are an important source of income for these regulatory agencies. However, previous spectrum auction design fail to take into consideration the effect of interference, which can adversely affect the truthfulness...
A cognitive radar can dynamically design its transmit waveform in response to changing environmental knowledge, which may be obtained a priori, estimated online, or both. We consider the detection of targets in wide-sense stationary additive colored Gaussian noise. Cognitive radar has been shown to provide potentially significant improvements for this problem. However, existing algorithms may be too...
The design of near-optimal detectors for binary signals in α-stable interference using two receive antennas is considered. The optimal detector requires more complex computation, whereas the linear (Gaussian) detector is practically simple but suffers from performance degradation with α-stable noise. In this paper, based on the optimal decision regions analysis, we propose to approximate the optimal...
