Títol:	Bit loading for MIMO with statistical channel information at the transmitter and MMSE receivers
Autor/a:	Hong, Li; Garcia Armada, Ana; Lozano Solsona, Angel
Abstract:	Comunicació presentada a: 2012 IEEE Wireless Communications and Networking Conference que va tenir lloc del 1 al 4 de abril de 2012 a Barcelona.
Abstract:	Bit and power loading schemes for a single-user multiple-input multiple-output channel using a minimum mean-square error receiver are proposed. Such schemes are derived without the benefit of instantaneous channel state information (CSI) at the transmitter, on the basis of only statistical CSI. They exploit the relationships between the average bit error probability at the receiver and the power allocation at the transmitter, in the context of spatially correlated Rayleigh fading. The performance of the proposed schemes is then benchmarked with respect to both non-adaptive transmission and to an adaptive counterpart with a zero-forcing receiver.
