Method and apparatus for designing frequency-spatial filter with variable bandwidth

摘要

Provided herein is a method and apparatus for realizing a frequency-spatial filter with variable bandwidth, the method including generating M number of FFT channel blocks having N number of channels by performing an N point FFT (Fast Fourier Transform) processing using M number of array antenna inputs; combining some of the N number of channels of each FFT channel block according to a frequency bandwidth variable parameter value; combining some of spatial response vector channels in a combined channel of each FFT channel block according to a spatial bandwidth variable parameter value; and combining all the channels and outputting the same.

1. A method for realizing a frequency-spatial filter with variable bandwidth, the method comprising:
executing by at least one controller processor non-transitory computer program code stored on storage media, the non-transitory computer program code comprising: program code that generates a first plurality of Fast Fourier Transform (FFT) channel blocks each having a second plurality of channels by performing second plurality point FFT processing using the first plurality of array antenna inputs; program code that combines at least two of the second plurality of channels of each FFT channel block according to a frequency bandwidth variable parameter value to provide a first combination; program code that combines at least two of spatial response vector channels in the combined channel of each FFT channel block according to a spatial bandwidth variable parameter value to provide a second combination; and program code that combines the second combination for each of the channel blocks to provide a third combination frequency-spatial filter with variable bandwidth.
