In this paper, we first present a successive interference cancellation (SIC) architecture for the V-BLAST system with asynchronous transmission mode, which is proposed in Shao and Tang (IEEE Trans Veh Technol 56(6):3827---3837, 2007) and characterized by achieving maximum possible diversity only by using a simple linear detection scheme under zero forcing (ZF) criterion. The SIC architecture that intuitively derived form the mathematical expression of the sampled output vector of a bank of matched filters at each receive antenna has a very low complexity, however, it can not employ the optimal detection order to minimize the propagation of errors from one step of detection to the next. Furthermore we find that it actually consumes extra energy of the previously detected signals to recover a signal. Therefore a ordered successive interference cancellation (OSIC) architecture is subsequently proposed to overcome the two shortcomings mentioned above. Simulations demonstrate that the OSIC in the asynchronous V-BLAST system can give much better performance at a little cost of complexity than it dose in conventional synchronous scheme.
