— In this paper, we study the power allocation scheme for a single user, multi-channel system, e.g. orthogonal frequency-division multiplexing (OFDM) systems, under time-variant wireless fading channels. We assume the receiver feeds back perfectly estimated channel state information (CSI) to the transmitter after a processing delay. The objective of the(More)
Paenibacillus polymyxa SC2 is an important plant growth-promoting rhizobacterium (PGPR). Here, we report the complete genome sequence of P. polymyxa SC2. Multiple sets of functional genes have been found in the genome. As far as we know, this is the first complete genome sequence of Paenibacillus polymyxa.
Paenibacillus mucilaginosus is a ubiquitous functional bacterium in microbial fertilizer. Here we report the complete sequence of P. mucilaginosus 3016. Multiple sets of functional genes have been found in the genome. To the best of our knowledge, this is the first announcement about the complete genome sequence of a P. mucilaginosus strain.
Conventional zero-forcing precoding was well investigated, but it hadn't considered the channel quality indicator (CQI) mismatch for practical system with limited feedback. This paper studies a novel zero-forcing precoding with channel quality indicator (CQI) estimation and adjusting, channel directional information(CDI) quantization, user scheduling and(More)
A method to design receive beamforming vectors with user selection is proposed for the multiuser Tomlinson-Harashima precoding, where each user is equipped with multiple antennas. The method exploits the relationship between LQ decomposition and Gram-Schmidt process to jointly optimize the receive beamforming vectors of users. Furthermore, a new approach is(More)
