Advanced Detection Algorithm for Multicode CDMA Systems with V-BLAST Architecture

摘要

High data rate can be achieved by multicode CDMA with V-BLAST architecture in wireless communications. An advanced detection algorithm, Order Partial Parallel Interference Cancellation with Decision Feedback (DF-OPPIC), is proposed to combat co-antenna interference and multiple access interference together in the system. Compared with the conventional algorithms, DF-OPPIC has better frame error ratio performance and lower arithmetic complexity.
