—Multi-user multiple-input and multiple-output (MU-MIMO) transmission scheme provides potential gain in terms of system capacity in spatial correlated scenarios and is considered as one of the key technologies in Long Term Evolution (LTE) systems. The goal of this paper is to gain insight into MU-MIMO detection concepts and their implementation aspects.(More)
—The multiuser multiple-input multiple-output (MU-MIMO) transmission scheme has drawn most attentions during the recent development of Long Term Evolution (LTE) systems. Based on the feedback information of the downlink channel, evolved NodeB may achieve multiple accesses via MIMO technology in MU-MIMO Transmission Mode and allow user equipments to share(More)
I. INTRODUCTION Multiuser Multiple-Input and Multiple-Output (MU-MIMO) systems have became promising in the context of achieving high data rates required for cellular standards after 3rd Generation (3G) of wireless systems. MU-MIMO is supported in 3GPP Long Term Evolution (LTE) Rel-8 to Rel-10 with codebook feedback based precoding for up to eight transmit(More)
—Wireless communication of multimedia signals is often based on the transmission of source codec parameters which are protected against channel noise by channel coding. Commonly, a cyclic redundancy check (CRC) is introduced in order to check for erroneous frames after error correction. If the CRC fails, a bad frame indication (BFI) flag is set which(More)
—Next generation long term evolution (LTE) systems evolve towards small cell networks (SCNs) to enable the tremendous data growth through extreme frequency reuse. However, shrinking the cell size to boost the spectral efficiency comes at the expense of increased co-channel interference (CCI) and is the dominant limiting factor from achieving higher network(More)
