Abstract

The V-BLAST system with asynchronous transmission mode first proposed by Shao can achieve full diversity only by using a simple linear detection scheme under zero forcing (ZF) criterion; therefore it gives a reasonable tradeoff between complexity and performance. In this paper, we propose two types of successive interference cancellation (SIC) detection schemes for the asynchronous V-BLAST system, one is characterized by applying M r successive interference cancellators before a maximal ratio combiner (where M t is the number of receive antennas), and the other has a maximal ratio combiner before a successive interference cancellator. Since Type I consumes more energy of the previously detected signals to recover a signal, Type II can offer a better performance and simulations demonstrate its validity.
