—In this work, an analytical coverage probability framework is derived for all the User Equipment (UE) types in a Fractional Frequency Reuse (FFR)-aided heterogeneous network leveraging tools of stochastic geometry. This framework is used to determine the minimum distance for edge femtocells to safely reuse same spectrum resources utilized by center macro users (MUEs) for successful signal tra...

It is well known that the spectrum efficiency (SE) and energy efficiency (EE) of wireless network have a tradeoff relationship. In cellular networks, the same frequency is reused among a number of cells and the frequency reuse factor (FRF) considerably affects the SE-EE tradeoff relationship in terms of the co-channel interference (CCI) and network capacity. In distributed antenna network (DAN)...

Dynamic spectrum auction is an effective solution to manage spectrum across many small networks. Yet without proper economic design, spectrum auctions can be easily manipulated by bidders, suffering huge efficiency loss. Selfish bidders can manipulate their bids, individually or in groups, to game the system and obtain outcomes that favor their own interests and hurt others. Prior solutions hav...

The integrated satellite and terrestrial network has become one of the frontier technologies next generation mobile communication system. is used as an extension supplement ground to achieve seamless coverage wireless communications. spectrum sharing realized from perspective planning, considering number co-frequency terminals distance between terminal center beam. existing schemes use concept ...

This paper proposes a frequency domain nulling filter and Turbo equalizer to suppress interference in the uplink of one-cell reuse single-carrier time division multiple access (TDMA) systems. In the proposed system, the desired signal in a reference cell is interfered by interference signals including adjacent-channel interference (ACI), co-channel interference (CCI), and intersymbol interferen...
