摘要
This paper presents a baseband real-time DSP implementation of a multiuser receiver built upon an improved strategy for parallel interference cancellation. Significant performance gains are obtained by using a partial parallel interference cancellation scheme that mitigates the negative effects of biased estimation and imperfect MAI cancellation that are intrinsic to the complete interference cancellation approach. An attractive feature of the implementation is that it has a computational complexity that is linear in the number of users. Experimental test results confirm substantial improvements over the conventional receiver.
