<p>Each complex signal sample a(k)+jb(k) of a frequency modulated signal is limited in order to reduce co-channel interference. The limiting is performed efficiently in a digital signal processor by determining a ratio r with a magnitude less than one, equal to b(k)/a(k) in a first case and a(k)/b(k) in a second case, determining from a look-up table a variable p with a magnitude equal to 1/X(1+r2), and determining a number equal to sgn(a(k))p(1 + jr) in the first case and sgn(b(k))p(r + j) in the second case as the limited output signal sample.</p> |
