+function rov = kaiser_rov(alpha)
+
+% KAISER_ROV returns the recommended overlap for a Kaiser window with
+% parameter alpha.
+% 
+% Taken from C code of Gerhard Heinzel:
+% 
+%    Compute the 'recommended overlap' (ROV) [%] of Kaiser windows
+%    from the parameter alpha. Best-fit polynomial
+%    was obtained from 180 data points between alpha=1
+%    and alpha=9.95. Maximum error is 1.5%, mainly due
+%    to insufficient precision in the data points
