this paper concerns the transmission of two independent gaussian sources over a two-user decentralized interference channel, assuming that the transmitters are unaware of the instantaneous csis. the availability of the channel state information at receivers (csir) is considered in two scenarios of perfect and imperfect csir. in the imperfect csir case, we consider a more practical assumption of...

Co-channel interference is recognized as one of the major factors that limits the capacity and link quality of a wireless communications system. An appropriate understanding of the statistical behavior of the co-channel interference is therefore required when analyzing and designing techniques that mitigate its undesired effects. The total co-channel interference in a wireless communications sy...

When investigating co-channel spatial reuse, typical studies on ad-hoc networks have adopted static, device-specific transmission/interference ranges regardless of the runtime environment. In this paper, we present an analytical framework to investigate co-channel spatial reuse in dense wireless ad-hoc networks based on RF propagation models for some common network topologies. We derive the min...

| A coherent CPM detector based on a reduced lter bank and a reduced state Viterbi decoder is proposed. Bit error probabilities of this detector for some CPM schemes satisfying a speciic narrow spectrum requirement mask are simulated for the AWGN channel. The performance for one of the good candidates is then further evaluated for the case when co-channel and adjacent channel interference is pr...

A coherent CPM detector based on a reduced filter bank and a reduced state Viterbi decoder is proposed. Bit error probabilities of this detector for some CPM schemes satisfying a specific narrow spectrum requirement mask are simulated for the AWGN channel. The performance for one of the good candidates is then further evaluated for the case when co-channel and adjacent channel interference is p...

By applying interference-aware channel segregation based dynamic channel assignment (IACS-DCA) algorithm, each access point (AP) can use a channel with low co-channel interference (CCI) in a distributed manner. Interference environment may vary due to e.g., switching on/off of APs. Its adaptability to varying CCI environment has been left as an interesting study. In this paper, we investigate t...

This paper presents a joint scheduling, beamforming, and resource allocation algorithm for multi-user wireless networks affected by co-channel interference. The analysis considers a network with one base station (BS) that uses a multiple antenna transmitter (beamformer) to schedule (in a time-division manner) transmissions towards a set of $J$ one-antenna terminals in the presence of $K$ persis...

In this paper a model to investigate the spectrum opportunities for cognitive radio networks in three radar frequency bands L, S and C at a specific location is introduced. We consider underlay unaware spectrum sharing model. The Secondary System we assume is an OFDM based system. The followed strategy is built upon defining a specific co or adjacent channel as a spectrum opportunity if -and on...

This paper studies signal detection in multiuser systems where the uncertainty is due to fading as well as a strong co-channel interference of the same form as that of the desired signal. In particular, unlike for the desired signal, no pilot for the interference signal is available for measuring its fading channel state. Still, the interference is a non-Gaussian process and treating it as Gaus...

In this paper, the relationship between the energy efficiency and spectrum efficiency in a two-cell cellular network is obtained, and the impact of multi-antenna on the energy efficiency of cellular network is analyzed and modeled based on two-state Markovian wireless channels. Then, the energy efficiency of multi-cell cellular networks with co-channel interference is investigated. Simulation r...
