MIMO transmission scheme for scalable video broadcast and multicast service

This paper presents a novel multi-input multi-output (MIMO) multicast and broadcast scheme for scalable video coding (SVC)-based transmission in the mobile system. This scheme provides differentiated video quality, that depends on the channel quality of the individual user, by employing different modulation and coding schemes (MCSs) for unequal error protection (UEP) of individual layers. Matching each SVC layer with individual antennas, packet-based successive interference cancellation (SIC) is performed to achieve a diversity gain in each layer, without knowing the channel condition for individual users in the broadcasting environment. Furthermore, we present an optimal power control scheme that can ensure the target service coverage, maximizing the average utility function for users in each layer.
