However, the dynamic changes in theAuthor: Anwer Al-Dulaimi, Saba Al-Rubaye, John Cosmas. The adaptive array offers higher gain, because of the precise pointing ability, than the switched beam array and greater interference rejection. Adaptive arrays may require longer computational time to converge to optimal patterns, and thus may not be suitable for real time high data rate communications where there are a large number of highly Cited by: 1. There is a consensus in the wireless communication industry [2] that the use of adaptive array processing technique is necessary for capacity enhancement and range improvement. Because the allocated frequency spectrum represents a significant capital investment, increasing the capacity of the cellular system will optimize the return on investment.
