hi,I wanna design a transmission link in Simulink.The data is Manchester coded.Then goes through Raised Cosine Filter with oversampling ratio 32,data rate 80kbps.Therefore:
1)Ts in Machester coding block is 1/80kHz=12.5*10^(-6),am I right?
2)For the Raised Cosine Filter block, the fc is 80kHz,fs is 80kHz*32=2560kHz.Sampling at 1/(2560kHz),is it correct?
3)After Raised Cosine Filter,it is ADC.The Low Pass Filter passband should be set to Pulse Width of the bit duration,Ts?Do I need to times with 1/fs or anything?
4)the AM modulated signal will come to Band Pass Filter as well.To set the lower Passband and Upper passband(rad/sec),do I need to divide the pass frequencies with fs as well?
Anyone can help me to solve this problem?Thanks for your kindness.
