一种新的子带自适应阵列处理算法

A Novel Subband Adaptive Array Processing Algorithm

子带自适应阵列处理可以实现并行计算,降低了计算复杂度,易于实时实现。但是多径延迟比较长时需要的子带数会很大,尤其在阵元数也比较多的情况下,需要计算的权值很多,会占用大量的硬件资源。提出了一种基于频域信道估计的子带自适应阵列处理算法。仿真结果表明,该算法可以获得和全子带自适应处理相当的性能,但是需要的计算量很小。

Subband adaptive array processing reduces the calculation complexity with parallel computing,and real-time implementation is easy to be carried out. However,it need a large amount of subbands if the multi-path delay is too long. Especially in the case of a bit more array’s sensors we need to calculate more weights,so that a large amount of hardware resources will be expended. A novel subband adaptive array processing algorithm based on frequency -domain channel estimation is proposed in this paper. The simulation results manifest that this algorithm could achieve the same performance as full SBAAP,while the calculation amount is small.
