Abstract―We have been proposing multi-beam MIMO (MBMIMO) as an Evolved UTRA downlink MIMO scheme for 3GPP long term evolution (LTE). MB-MIMO is a pre-coding MIMO scheme that uses...
Abstract - The RoQ (Reduction-of-Quality) attacks are lowrate DDoS attacks that degrade the QoS to end systems stealthily but not to deny the services completely. These attacks are...
Abstract— Adding SDMA capabilities to modern wireless communication systems like IEEE 802.16 WiMAX promises high system capacity gains but raises the problem of combining orthogo...

Abstract—In this paper we propose a low complexity frequency domain channel estimator for pilot-symbol-assisted (PSA) orthogonal frequency division multiplexing (OFDM) systems in...
Abstract—In [1], the author presented a 1+N protection strategy against single link failures using a network coding approach on p-Cycles. In this paper, we extend this approach t...
