Enhanced Multimedia Broadcast/Multicast Service (eMBMS) is a new function defined in 3GPP specification to support PTMP (point to multiple points) transmission in LTE networks. In order to improve reliability, two mechanisms are implemented in single-cell eMBMS: (1) Raptor is implemented at the eBMSC (Enhanced Broadcast/Multicast Service Center) to provide packet-level protection; (2) HARQ is used...
Enhanced Multimedia Broadcast/Multicast Service (eMBMS) is a new function defined in 3GPP Release 8 specification, which supports download delivery and streaming delivery to group users in LTE mobile networks. For download delivery, there are two mechanisms implemented in different entities to improve reliability: (1) At eBMSC (Enhanced Broadcast/Multicast Service Center), Raptor code is implemented...
Enhanced Multimedia Broadcast/Multicast Service (EMBMS) is a new function defined in 3GPP specification, which supports download delivery and streaming delivery to group users in LTE mobile networks. In 3GPP Release 8 specification, the EMBMS transmission is classified into single-cell transmission and MBSFN (Multicast Broadcast Single Frequency Network transmission). In MBSFN, the statistical multiplexing...
This work studies the performance of a data-driven reduced rank scheme for rapid timing acquisition in multiple access communications. Our results show that when only a limited amount of preamble bits are available, instead of the true second-order statistics (SOS), the reduced rank scheme provides reliable timing information. Exploiting the structure of the multiple access interference, the data...
