An iterative algorithm for linear inverse problems with compound regularizers
In several imaging inverse problems, it may be of interest to encourage the solution to have characteristics which are most naturally expressed by the combination of more than one...

A New Two-Step Precoding Based on Rotation Transformations in Closed-Loop MIMO Systems
— In this paper, we propose a two-step precoding approach for multiple-input multiple-output (MIMO) systems by dividing the precoding process into two steps: spatial multiplexing...

Clock-frequency assignment for multiple clock domain systems-on-a-chip
Modern systems-on-a-chip platforms support multiple clock domains, in which different sub-circuits are driven by different clock signals. Although the frequency of each domain can...

A Novel ZF Detection Scheme for Double SFBC based OFDM System in Frequency Selective Fading Channel
Abstract— In this paper, we propose an efficient low complexity MIMO detection method for double space-frequency block coded (D-SFBC) OFDM system. The proposed MIMO detector inv...
