Fusion of Respiratory Rates

The third fundamental stage of the RR algorithms is 'Fusion of Respiratory Rate Estimates', in which multiple RR estimates are fused to provide one single output. This stage is optional.

Specify the interchangeable technique(s) for Fusion of RR Estimates

The techniques to be used for fusion of RR estimates must be specified. A brief description of each technique is provided in this publication. Use the following settings in setup_universal_params.m to specify all implemented techniques for use on both ECG and PPG signals:

`up.al.options.fuse_rr = {'fus_mod', 'fus_temp'};`

`up.al.sub_components.fus_mod = {'SFu', 'SPA', 'PMC', 'PRC'};`

`up.al.sub_components.fus_temp = {'TFu'};`

The techniques can be split into modulation- and temporal-fusion techniques. The modulation-fusion techniques are as follows:

1. Smart Fusion (SFu , ref)

2. Spectral peak-conditioned averaging (SPA, ref)

3. Pole magnitude criterion (PMC, ref)

4. Pole ranking criterion (PRC, ref)

The temporal-fusion techniques are as follows:

1. Temporal smoothing (TFu, ref)
