Executive Summary

In this paper, the authors consider the multicast channel in a cellular network wherein all the users within a cell request a common information stream from the base station. In addition to data streaming this can also model control channels in the cell as opposed to the regular data channels used for user specific information transmission. While the multicast transmission in a single cell environment has been intensively analyzed in the literature, the focus in this paper is on a scheme that uses differential time diversity transmission and accumulates signal samples for final decision in order to suppress the inter-cell interference. They will show that this approach offers a superior system performance with respect to the existing schemes.
