代码说明:

  到达时间差(TDOA)源位置估计 -------------------------------------------------- ---------- 使用麦克风信号和自由场模型之间的延迟源位置估计。 TDOA_pairs.m 估计延迟(相对于通道1)通过互相关在时域中。 TDOA_pairs_GCC.m 估计在频域中的延迟(相对于信道1)。采用广义互相关 和SCOT或PHAT(或没有)的均衡。 PHAT的建议,以避免因周期分量的含糊之处。 TDOA_to_sourcepos.m 估计源位置(距离和垂直RESP。水平偏移量)从之间的延迟 阵列麦克风信号。假设一个自由场。(Direction of arrival (DOA) estimation ------------------------------------- Direction-of-arrival estimation with a free field, far field model. Narrowband or broadband (non-coherent) processing. DOA_Bartlett.m Bartlett (delay-and-sum) steered response power. DOA_Bartlett_Octave.m Bartlett (delay-and-sum) steered response power within nth octave frequency bins. DOA_MUSIC.m MUSIC based pseudo beamform power. DOA_MUSIC_Octave MUSIC based pseudo beamform power. nth octave filtering.)
