A n e w j o i n t detection m e t h o d based o n s p h e r e packing lattice decoding is presented. T h e alg o r i t h m is suitable for b o t h synchronous a n d asynchronous CDMA-DSSS systems, a n d i t may detect up to 32 users w i t h a reasonable complexity. T h e complexity is i n d e p e n d e n t of t h e modulation size.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
