Abstract :
This paper presents a new ordering criterion for successive interference cancelations (SIC) in MIMO flat fading channels and provides a performance comparison with the original ordering of V-BLAST. Furthermore, an efficient and stable Cholesky decomposition based detection algorithm is proposed to further reduce the computational complexity of existing fast algorithms for SIC in MIMO flat fading channels.
