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...
—This paper proposes an algorithm for the adaptive adjustment of the transmission rate of VoIP sources based on the voice quality estimated at the receiver. This adjustment is ac...
—The emerging IEEE 802.11e standard is expected to provide service differentiation and resource allocation for realtime traffic. To support the transmission of voice and multime...
