Algorithm 2 Enhanced Polarization Estimation

Input:  $[s_{x,m}^{\prime }\left[i\right],s_{y,m}^{\prime }\left[i\right]]$, $m=0:M-1$, $i=0:I^{{}^{\prime }}-1$; Output:  $\widehat{\gamma }$, $\widehat{\eta }$;  1:for$i=0:I^{{}^{\prime }}-1$do  2:    Calculate $q_{x,y}^m\left[i\right]$ by (20) and $[p_x^m\left[i\right],p_y^m\left[i\right]]$ by (21),       $m=0,\dots ,M-1$;  3:end for  4:Compute $U+jV$ by (24);  5:Determine $(\widehat{\gamma },\widehat{\eta })$ by (23),  6:Calculate $s_c\left[i\right]$ by (26);  7:Determine the real estimate $\widehat{\gamma }$ by (27).
