Conventional phase unwrapping methods require a continuous CPS that starts at zero frequency or at a frequency with a known unwrapped phase. A novel phase unwrapping method is proposed herein that is capable of carrying out the task without these requirements. The proposed method is applied to direction-of-arrival (DOA) estimation for a bandpass signal—a case that conventional methods are unable to handle. Analytical performance and experimental results confirm the effectiveness of the proposed method.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2010 EURASIP||Keywords:||Direction-of-arrival;Phase unwrapping;Cross-power spectrum (CPS)||Language:||en||Status of Item:||Peer reviewed||Conference Details:||18th European Signal Processing Conference (EUSIPCO-2010), Aalborg, Denmark, 23 - 27 August, 2010|
