Hi there, I have been simulating a system in matlab. So Im not good with communication basics and im very new to it. Here is the problem. Im using rectpulse function from matlab, the it needs a sampling rate to generate rectpulse from random bits. So the sampling rate is calculated using, [tex]n=sampling frequency/bit rate,[/tex] [tex]n=sampling frequency*period[/tex] say period is Tb, bit rate is Rb, sampling frequency is fs. [tex]Tb=1/Rb[/tex] So my problem is, i dont know the unit of n, as i understand n is the sampling rate, its not the sampling time, what it is actually, im really lost, i tried a lot of resources, i still dont understand. How can i find out the maximum frequency. And say i want to generate different maximum frequency for this rectpulse, i should know the frequency first which i dont know now, i dont know how to change it, Please someone help me. Thank you. Its urgent.
