Fast root music algorithm
WebTo summarise, the proposed fast root-MUSIC algorithm for arbitrary arrays can be accomplished via the following steps: 1. Compute the sampling matrix G(r). Note that this offline process requires to be done only once for a given array. 2. Form the received data covariance matrix and perform eigenvalue WebDec 6, 2024 · Ten groups of experimental data were put into the MCSPO-MUSIC algorithm; the root mean square errors (RMSE) of the localization errors are 1.91° (non-sparse array) and 3.12° (sparse array), respectively. Finally, the blind source separation algorithm was used to remove the field noise, which verifies the algorithm and sparse concept accurate ...
