The number of iterations is typically set to the sparsity level K of the block-sparse vector to be recovered. The sparsity level K is dependent on the number of the received polarised sources. Therefore, the sparsity level K is unknown due to the unknown number of sources.

For other scan … WebJul 25, 2024 · The proposed message passing based BSBL (MP-BSBL) algorithm has a complexity independent of active user number, which can be significantly lower than that of the BOMP algorithm. In addition, MP-BSBL provides an estimate of the noise power, which can be readily used for data detection.
Weband Vandergheynst, 2008). We extend the BOMP algorithm to the case with block coherent dictionary by using a sensing dictionary. The sensing dictionary we used has the same size as the ordinary dictionary, that is, d NpΨ∈ ×. Therefore, the modified BOMP selects a block at sensing step according to: 1 2 argmax [ ] .H k k i i i= Ψ r − (10) WebTowards this end, we propose the best-O message passing (BOMP) algorithm for SCSPs and VCSPs. We prove that, unlike other standard message passing algorithms which are in general not guaranteed to converge, the BOMP algorithm guarantees convergence for SCSPs and specific subclasses of VCSPs.
