In this paper, we consider a system based on Orthogonal Frequency Division Multiple Access (OFDMA) and investigate the benefits of combining the Satisfaction Oriented Resource Allocation (SORA) algorithm, which aims at maximizing the number of satisfied users in a system, and Orthogonal Random Beamforming (ORB), which provides spatial multiplexing gains and has low computacional complexity, low signaling...
This correspondence corrects an error in the proof for theorem, the concavity of the logarithmic function was incorrectly applied to obtain the sum-rate lower bound even though it leads to an upper bound. The revised proof is provided in section II-A, where the aforementioned error has been removed. The changes include replacing the average of a set of signal-to-noise- interference (SINR) terms with...
This paper studies efficient complex valued matrix manipulations for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions...
