Interference coordination methods for Evolved-Multimedia Broadcast/Multicast Service (E-MBMS) in Long Term Evolution Advanced (LTE-A) are presented. In this paper, OFDM/OFDMA signals based on LTE parameters are combined with MIMO, Turbo codes and signal space diversity methods. Different interference coordination techniques, such as, MIMO coordination, Fixed Relay stations and adaptive frequency reuse...
Hierarchical constellations constitute a simple technique for achieving multiresolution and, therefore, are appealing for MBMS (Multimedia Broadcast and Multicast Service). In this paper we consider the use of M-QAM hierarchical constellations (Quadrature Amplitude Modulation) combined with MIMO (Multiple Input Multiple Output) for the transmission of multicast and broadcast services in UTRA (Universal...
Among radio technologies, multiple-input multiple-output (MIMO) systems have attracted wide research interests in recent years. It is widely recognized that MIMO systems can be employed for achieving a high capacity and a high diversity order, for mitigating the effects of various types of interfering signals, and for supporting space-division multiple-access (SDMA). In this study a MIMO assisted...
