Performance Analysis of CMA Adaptive Array in Reducing Interference in Mobile Communications
Wu hui-lan · Telecommunication Engineering · 2002
CMA adaptive array has the capability to reduce multipath interference and cochannel interference (CCI). In this paper,the performance of CMA array in reduing multipath interference and CCI is analyzed,and computer simulations are also been carried out.The results of simulations show that the random phase shift,the amplitude and DOA(Direction of Arrival) of signals can influence performance of CMA array in reducing multipath interference.However,CMA array has a better performance in reducing CCI than that in reducing multipath interference.If the CCI signals are not in the same direction of desired signal,they can be reduced by CMA array.
