cma equalizer and cpbfsk

Started by Fredrik April 4, 2006
Hi!

Will a constant modulus algorithm work for a cpbfsk signal even it's not
i.i.d (independent identically distributed) ?

Thanks

I suppose it could be, but since there is no information in the amplitude of the bfsk signal why bother to equalize it? -Clark

The amplitude might be modulated due to fading. CMA designs a FIR filter that tries to restore the amplitude to a constant. In the process, it cleans up the fading-induced ISI and thus improves BER. John
