Multicasting is a spectrally efficient method for supporting multimedia communication by allowing transmission of packets to multiple destinations using fewer resources. To incorporate cooperative (distributed MIMO) diversity, Cooperative Extended Balanced Space-Time Block Codes (CEBSTBCs) have been proposed providing full diversity when one or more feedback bits are sent back via feedback channel. However, the CEBSTBCs are designed for unicast delivery in the literature. This paper presents a novel wireless multicasting scheme which selects the optimum CEBSTBC for all mobile users to support wireless multimedia multicasting. Extensive, detailed simulations are performed to show the feasibility of full rate and full diversity multicast service provisioning in Rayleigh fading channels.
