Complexity Comparison between Two Optimal-Ordered SIC MIMO Detectors Based on Matlab Simulations
Yanpeng Wu, Hufei Zhu
This paper firstly introduces our shared Matlab source code that simulates the two optimal-ordered SIC detectors proposed in [1] and [2]. Based on our shared Matlab code, we compar…
Inverse LDM' and LU Factorizations of a Partitioned Matrix with the Square-root and Division Free Version for V-BLAST
Hufei Zhu
This letter proposes the inverse LDM' and LU factorizations of a matrix partitioned into 2x2 blocks, which include the square-root and division free version. The proposed squareroo…
