| Abstract : This paper is concerned with introducing a direction of arrival estimation (DOA) estimation algorithm that is independent of the bandwidth of the intercepted signals. The proposed algorithm offers a modification to most subspace based DOA estimation algorithms that depend basically on narrowband signals assumption. The basic idea of this modification is the replacement of conventional correlation matrix by a cyclic one. This modification enables the proposed algorithm to deal with both narrowband and wideband signals. In addition, this algorithm requires only that the interference signals are cyclically uncorrelated with SOI. This condition is easier to be achieved than uncorrelation condition that is required by conventional algorithms. Computer simulations using an additive white Gaussian noise (AWGN) channel show that the proposed DOA estimation algorithm succeeds to estimate DOAs of the SOI and interference signals at 10 dB signal to noise ratio and -3 dB signal to interference ratio. | ||||
