Abstract
In this paper we consider a multiple input multiple output
multi-group space-time coding system that is a
combination of V-BLAST and space-time block codes.
Decoding order is an important issue for serial group
interference cancellation (SGIC) algorithm. Different
ordering schemes for SGIC are compared. While layers in
SGIC suffer from unequal receive diversity, parallel group
interference cancellation (PGIC) has the potential to
achieve full receive diversity for all the layers.
Performance of both the algorithms are analyzed and
