Fast ambiguous DOA elimination method of DOA measurement
Three high-performance DOA estimation methods were proposed in [4] for eliminating phase ambiguity of massive hybrid MIMO systems, and the Cramer-Rao lower bound (CRLB) was derived. In [6],...

High-Accuracy DOA Estimation Algorithm at Low SNR Through Exploiting a
Performance of direction of arrival (DOA) estimation is one of the most important issues in array signal processing. Subspace-based algorithms provide a good compromise between the estimation accuracy and computational complexity. However, these methods are exposed to performance breakdown at low SNR scenarios. A major reason for such performance breakdown is the subspace swap phenomenon
- What is defence acquisition procedure (DAP 2020)?
- The Defence Acquisition Procedure (DAP 2020), which supersedes the Defence Procurement Procedure 2016 (DPP 2016), is a sincere effort by the Ministry of Defence to improve the capital procurement procedure.
- What is DAP 2020?
- Ibid, Chapter I, Para 1, p. 1. (DAP 2020). Like its predecessors, the DAP-2020 contains several statements and provisions that require to be pieced together to get an idea of its underlying policy orientation.
- What is dap-2020?
- The DAP-2020 is a sincere effort by the MoD to improve the procurement procedure, but it is replete with several concepts and ideas, some of which are ambiguous and lack clarity of purpose.
- Does a fixed number of antennas affect the DOA methods complexities?
- Indeed, the DoA methods complexities were evaluated w.r.t. the variation of the number of sources in the range (mathcal {L} in {1:1:128 }) under a fixed number of antennas M = 256.
- What is the performance versus complexity tradeoff of different DOA methods?
- In this section the performance versus complexity tradeoff of various DoA methods discussed previously is compared by means of figure-of-merits, namely DoA error and scattering of estimation. In this sense, the error of amplitude of the scanning methods DS, MVDR, MUSIC and FT-DoA, as well as the DoA error of all methods are analysed.
- What is HPCA 2025?
- HPCA is a high-impact premier venue for presenting research results on a wide range of computer architecture topics. Some topics of interest are listed below, but we encourage authors to contact the program chair if they have a question regarding the topic fit: HPCA 2025 features a separate Industry Track with a separate call for papers.
