dc.description.abstract | In this paper, a new direction-of-arrival (DOA)
tracking algorithm, direction lock loop (DiLL), is proposed for wireless direct-sequence code-division multiple-access systems. It has a similar concept to the delay lock loop that is used for timing synchronization. It may track the DOA of sources by iterations. Its computational requirements are + O( ) for coherent DiLL and 2 + O( ) for noncoherent DiLL, where is the number of antenna elements and is the number of signal sources, which is less than that of the projection approximation subspace tracking with deflation algorithm [5]. The DOA tracking accuracy is demonstrated by analysis and computer simulations. | en |
