— An exact and closed-form expression for the average bit error rate (BER) of coherent binary phase-shift keying (BPSK) using maximal ratio combining (MRC) in the presence of mul...
— In this paper, we propose a new carrier frequency offset (CFO) tracking algorithm for orthogonal frequency division multiplexing (OFDM) systems. Assuming that the channel remai...
—In this paper, we extend both Bianchi’s and Kumar’s models and characterize the channel activities governed by IEEE 802.11 DCF in multi-hop wireless networks from the perspe...
IEEE 802.11e is a wireless local area networking standard introducing quality of service. It defines new MAC protocols, mainly HCF and EDCF. EDCF is a contentionbased channel acce...
