Computation afford of adaptive antenna technology is the key factor limited its applications. This paper presented a new two-stage structure to solve this problem. By dividing array antennas into two group, two–stage structure can reduce computation afford with the same system performance of one-stage structure as the traditional adaptive antenna technology does. Algorithm and criterion in each stage can be selected independently according to the applications situations. Theoretical analyses of system performance in two-stage and one-stage structures are presented, and computation simulations are performed using RLS algorithm. Due to the low-complexity and low-computation, more antennas can be used to improve performance. For diversity receiving, it can help to improve SNR and less computation afford is obtained with the same performance as the traditional processing structure. The presented two-stage structure can be generalized easily to multiple–stage structure.
