Spectrum efficiency with correlated interferers
5th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, Wireless Networks - Catching the Mobile Future., 2002A general formulation of the probability of co-channel interference (PCI), valid for macro- and micro-cellular radio systems, is presented and related to spectrum efficiency in a correlated log-normal shadowing and Rician/Rayleigh fading environment. The effects of correlation between the signals and of the Rice factors of the Rician faded desired and ...

On Cellular MIMO Spectrum Efficiency
2007 IEEE 66th Vehicular Technology Conference, 2007To increase the transmission rate without bandwidth expansion, multiple-input multiple-output (MIMO) technique has been attracting much attention. When MIMO technique is applied to a cellular system, the MIMO channel capacity is affected by the interference from neighboring co-channel cells.

Spectrum- and energy-efficient D2DWRAN
IEEE Communications Magazine, 2014IEEE 802.22 is the first world-wide standard for wireless regional area networks using cognitive radio technologies. Major drawbacks of these networks are limited network capacity and low energy efficiency. One potential solution for these drawbacks is device-to-device communication, which can be incorporated as D2DWRAN.

Spectrum pooling: an innovative strategy for the enhancement of spectrum efficiency
IEEE Communications Magazine, 2004This article describes the technical challenges that have to be met when implementing the interesting new technology of spectrum pooling. This notion represents the coexistence of two mobile radio systems within the same frequency range. It enables the secondary utilization of already licensed frequency bands as aimed at by several regulatory ...

Efficient spectrum summarization using compressed spectrum scans
IEEE INFOCOM 2018 - IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2018We present AirPress, a spectrum scan compression method that leverages wavelet decomposition for lossy compression of spectrum data and allows up to 64:1 compression ratio of power spectral density traces without adversely impacting the spectrum summarization accuracy.
