1-Bit compressed sensing of positive semi-definite matrices via rank-1 measurement matrices

ICASSP 2016accepted

In this paper, we investigate the problem of recovering positive semi-definite (PSD) matrix from 1-bit sensing. The measurement matrix is rank-1 and constructed by the outer product of a pair of vectors, whose entries are independent and identically distributed (i.i.d.) Gaussian variables. The recov…

Joint group power allocation and prebeamforming for joint spatial-division multiplexing in multiuser massive MIMO systems

ICASSP 2015accepted

We investigate the joint optimization of the group power allocation and prebeamformer for joint spatial division and multiplexing (JSDM) in massive MIMO downlink systems. In contrast with the approximated block diagonalization (ABD) prebeamformer which is derived by heuristic method in the original…
