Reduced-complexity iterative multiuser detectionscheme for CDMA
Jiachun Pan, Cheong Boon Soh, Endra Gunawan · Electronics Letters · 2000
A simple way of choosing only K + 1 user bit vectors instead of the full-complexity 2K in the likelihood computation for iterative multiuser detectors for code division multiple access systems is presented. An alternative, reduced computation method of increasing this list of vectors after each iteration is also presented.
