Using Matlab $($or any software$),$generate a binary data waveform at $4$Mbps rate. Perform a QPSK modulation on the data,

over a carrier at $1900$MHz$.$Map bit $1$to $+1$V and bit $0$is represented by $-1$V$.$Use pulse$-$shaping filter to convert the square

pulses into root raised cosine pulses with a roll$-$off factor of $0\mathrm{.}35.$What is the symbol rate? What is the data rate?

Q$7$Show the spectrum of the modulated signal for roll$-$off factor of $0\mathrm{.}01,0\mathrm{.}35,0\mathrm{.}5,$and $1$on a same plot. For each roll$-$off factor,

compute the bandwidth. What can you conclude?

Q$8$Plot the transmit and receive eye diagram corresponding to a roll$-$off factor of $0\mathrm{.}35$with an Eb$/$No of $15$dB$.$

Q$9$Plot the transmit and receive constellation $($overlap$)$corresponding to a roll$-$off factor of $0\mathrm{.}35$with an Eb$/$No of $15$dB$.....$Hi$,$ I received an answer from one expert, but couldn't get the Matlab code going. $...$If u could please get me the correct Matlab code and also check if it runs before posting the answer. Answers must be in Matlab Thank u$.$
