denoted by $ (\gamma _i,\theta _i) $ where $ 1\leq i\leq N_W $.

2.  For the singular fade state $ (\gamma_1, \theta _1) $ in $ \mathcal{H}_W $, identify the set of class distance functions in $ d_{\bar{\mathcal{C}}}(\gamma , \theta) $ that reduces to zero at that singular fade state $ (\gamma_1, \theta_1) $. Choose the one among them, which is minimum in that set for all values of $ (\gamma, \theta) \neq (\gamma_1, \theta_1) $. (From Lemma \[lemma:ordering\], there is always only one such class distance function.) Let this class distance function be $ d_{\mathcal{C}_{k_1}}(\gamma ,\theta) $ corresponding to distance class $ \mathcal{C}_{k_1} $. Repeat this for all $ (\gamma_i, \theta_i) \in \mathcal{H}_W $, to obtain a set of class distance functions $ \lbrace d_{\mathcal{C}_{k_i}}(\gamma, \theta) $, $ 1 \leq i \leq N_W \rbrace $. Each $ d_{\mathcal{C}_{k_i}}(\gamma, \theta) $ reduces to zero at the singular fade state $ (\gamma_i, \theta_i) $. This is the set of all possible class distance functions other than $ d_{min}(\mathcal{S}) $, that can possibly produce the minimum distance in $ \mathcal{S}_{\text{eff}} $.

3.  To find the region $ \mathcal{R}_W(\mathcal{C}_{k_i}) $, we need to obtain the values of $ (\gamma, \theta) \in \, \text{wedge}\,
