An analytical evaluation of bit error probability in mobile radio systems with 12PM3 modulations

An analytical method is presented for the error probability evaluation that can be used in many cases to reduce significantly the computation time with respect to that required by simulation techniques. The method can take into account thermal noise, intersymbol interference caused by intermediate frequency (IF) and baseband (BB) filterings, multipath propagation with typical delay spreads, Rayleigh fading, and random FM noise. A number of results are presented relevant to multipath fading channels with different vehicle speeds, several modulation techniques belonging to the 12PM3 class with frequency discriminator detection and different IF and BB filters.<
