Message Passing in C-RAN: Joint User Activity and Signal Detection
Yuhao Chi, Lei Liu, Guanghui Song +3
In cloud radio access network (C-RAN), remote radio heads (RRHs) and users are uniformly distributed in a large area such that the channel matrix can be considered as sparse. Based…

Sparse Vector Recovery: Bernoulli-Gaussian Message Passing
Lei Liu, Chongwen Huang, Yuhao Chi +3
Low-cost message passing (MP) algorithm has been recognized as a promising technique for sparse vector recovery. However, the existing MP algorithms either focus on mean square err…

Asymptotically Locally Optimal Weight Vector Design for a Tighter Correlation Lower Bound of Quasi-Complementary Sequence Sets
Zilong Liu, Yong Liang Guan, Wai Ho Mow
A quasi-complementary sequence set (QCSS) refers to a set of two-dimensional matrices with low non-trivial aperiodic auto- and cross- correlation sums. For multicarrier code-divisi…
