摘要：
A subband adaptive beamformer with general parameter filter banks (GPFB) for broadband array antennas is presented, which is used to enhance performance of suppressing the interference and accelerate convergence speed of weights. Instead of the conventional FFT filter banks, GPFB are utilized to partition the frequency band into several subbands without aliasing between them almost. Simulation results demonstrate that as subbands running at downsampling and in manner of parallel, the loads of computational processing costs, compared with traditional fullband methods, can be alleviated, deep suppression of the interference and convergence speed of weights are also improved.
