It is widely recognized that OFDM modulations (Orthogonal Frequency Division Multiplexing) are suitable for broadband wireless systems. For this reason they were selected for several digital broadcast systems and wireless networks and are being considered for UTRA (Universal Mobile Telecommunications System Terrestrial Radio Access) Long-Term Evolution (LTE). Regarding LTE UTRA, special attention is being devoted to the support of Multimedia Broadcast and Multicast Service (MBMS) which has already been standardized in 3GPP UTRAN (UTRA Network). The goal is to enable an efficient support of downlink streaming (from the base station to the mobile terminal) and download-and-play type services to large groups of users.
