This paper presents a new space-time two-stage receiver with the assistance of soft information for the Alamouti space-time block code (STBC) and spatially multiplexing (SM) combined systems. The first stage of the receiver consists of a set of soft generalized sidelobe canceller (GSC)-based detectors, each for every STBC group and is intended to yield a more precise initial estimate of the transmitted...
This paper investigates the impact of femtocell interference on existing macrocells with fractional frequency reuse (FFR). Instead of using complicated transmission techniques by coordinating multiple base stations (BSs), this paper adaptively configures FFR pattern to avoids interference caused by femtocells, depending on density and locations of femtocells. Simulation results show that the proposed...
In this paper, interference mitigation through downlink power control is considered for macrocell Femtocell overlay. Specifically, the strong interference in the downlink from the home base station to a nearby macrocell user should be properly controlled such that the quality-of-service of both the macrocell user and the Femtocell users can be guaranteed. In this work, the fundamental capacity limitation...
This paper focuses on transmit pre-coding for multiuser multi-input multi-output (MU-MIMO) downlink channels. Multi-user interference (MUI) and noise are main factors that affect the performance of MU-MIMO system. Besides, the system performance will degrade as the receive power on different antennas gets unbalanced. The Block-diagonalization (BD) algorithm eliminates the MUI completely. However,...
