An Efficient Sic Detection Algorithm for 64-Qam Mimo Systems
Main Article Content
Abstract
In real propagation environment, channel reuse causes co-channel interference which will degrade MIMO channel performance. A
Successive Interference Cancellation (SIC) detection algorithm with 64-QAM technique is used to improve the quality of received signal in a
high interference environment. Using Concatenating MMSE with SIC equalization, better cancellation gain can be achieved. In this paper,
MMSE-SIC-SORTING has been presented, whose performance is better in high interference environment when compared to the earlier
detection schemes like ZF,ZF-SIC,ZF-SIC-SORTING,MMSE,MMSE-SIC etc,.
