A new method based on improved multiple signal classification (MUSIC) algorithm and independent component analysis (ICA) method is applied in this paper. In contrast with the original MUSIC algorithm, the proposed version can give good performance at lower signal/noise ratio (SNR). After estimating the frequencies accurately, the amplitudes and phases of interharmonics are calculated with ICA method...
Performance of high resolution direction finding is degraded in the presence of mutual coupling existing among antenna array elements. There are different methods to calculate the mutual coupling matrix and compensate its effects in the DF algorithm performance. In this paper, the multiple-signal classification algorithm is used to find the angle of arrival in the uniform circular array. According...
This paper presents a new method for estimating the direction of arrival (DOA) of source signals whose number N can exceed the number of sensors M. Subspace based methods, e.g., the MUSIC algorithm, have been widely studied, however, they are only applicable when M > N. Another conventional independent component analysis based method allows M ges N, however, it cannot be applied when M < N....
