摘要

我们介绍了超指令波束形成器的一种新实现。新结构具有降低计算复杂度的优点。这种优势是由于gsc(广义旁瓣抵消)方案。与传统的GSC不同，旁瓣抵消路径中的滤波器是固定的，可以使用维纳解提前计算。新结构的降噪性能与超定向波束形成器完全相同。

An alternative implementation of the superdirective beamformer

We introduce a new implementation of superdirective beamformers. The new structure has the advantage of reduced computational complexity. This advantage is due to a GSC-like (generalized sidelobe canceller) scheme. Unlike the conventional GSC, the filters in the sidelobe cancelling path are fixed and can be computed in advance by using the Wiener solution. The new structure yields exactly the same noise reduction performance as the superdirective beamformer does.
