BER-Allocation in MIMO and MIMO-OFDM
2006 IEEE International Symposium on Information Theory, 2006Adaptive bit loading algorithms are proposed for MIMO and MIMO-OFDM systems, thus better exploiting space and frequency diversity. Constant power allocation is assumed over all subchannels while the bit error rate is unconstrained. An efficient bit loading algorithm, which maximizes system bit rate under target mean BER restriction is formulated for a ...

Downlink MIMO in LTE-advanced: SU-MIMO vs. MU-MIMO
IEEE Communications Magazine, 2012Single-user multi-antenna technologies are well upported in current standard specifications like LTE Release 8/9. Further development of the specification (LTE-Advanced) is expected to conform to the requirements for IMT-Advanced systems. One of the key enabling features of LTE-Advanced to meet IMT-Advanced downlink performance requirements is multi ...
