Wireless Communications 2nd edition by TS Rappaports problem

Wireless Communications (2nd edition) by T.S. Rappaport\'s problem number 6.15. The question says:-
Design a raised cosine roll-off filter for Ts = 1/24300 S and Alpha =0.35. Write expressions for, and plot, the impulse response and the frequency response of the filter. If this filter were used for 30 kHz RF channels, what percentage of the total radiated energy would fall out-of-bound? Computer simulation or numerical analysis maybe be used to determine results.

So I need a MATLAB Code to plot the frequency response of the filter. I am stuck in that because it\'s frequency response Hrc(f) is given as a function with 3 values for different ranges :-

So, I need a MATLAB Code to plot Hrc(f).
Thanks.

(c) What is the absolute bandwidth of the RF spectrum if raised cosine tol for -1/37 Assume BPSK is used. loft pulses are used, (d) If a timing jitter of 1o-6 secoeds exists an the receiver and raised cosine rolloff pulses are used, will the detector experience intersymbel interference from the adjacent synbalst Explain. (e) If GMSK modulation is to be generated as shown and a 3 dB handwidth of 500 kHz is used for the Gaussian low pass filter, what is the proper choice for the PM peak frequency deviation, (0) For GMSK modulation using BTs0.5, how many spectral sidelobes cccur? 6.13 If a mobile radio link operates with 30 dB SNR and uses a 200 kHz chanmel, find the theoretic maximum data capacity possible. How does your answer compare to what is offered hy the GSM standard, which operates at a channel rate of 270.8333 kbps? 6.14 Compare the channel spectral efficiencies of IS-54, GSM, PDC, and IS-95. What are the theores- ical spectral efficiencies for each of these standards if they operme at 20 dB SNR? 6.15 Design a raised cesine rolloff filter for T. = 1/24300 s and -035. wme expressions for, and plot, the impulse response and the frequency response of the filter. If this filter were used for 30 kHz RF channels, what percentage of the total radiated energy would fall out-of -band? Com- pater simulation or numerical analysis may be used to determine results 6.16 Design a Gaussian pulse-shaping fl ter with BT 0.5 for a symbol rate of 19.2 kbgs. Wnite expressions for, and plot, the impulse response and frequency response of the filter. If this filber were used to produce GMSK in 30 k RF channels, what percentage of the total radiated energy would fall out-of-band? Repeat for the case of BT-0.2, and BT-0.75. Computer simu lation or numerical analysis may be used to determine results. Simply apply a random NRZ binary waveform through a Gaussian pulseshaped filter and then FM modulate, as in Figure 6.42. Be sure to include all documented source code, and clearly label all axes and document and display the PSD and spectral occupancy in relation to R, for varying values of BT 6.17 GMSK Computer Simulation: Recreate Table 6.3 and Figure 6.41 using computer simulation. 6.18 Derive Equation (6.106) for an MSK signal, hMSK ansmitter and receiver shown in

Solution

Ted Rappaport was born in Brooklyn, big apple and enraptured around plenty as a child; [15] he was a senior at Lincoln highschool in Cambridge town, IN [16] once his oldsters told him to depart as a result of as Rappaport explained in associate interview, \"They would say i used to be rebellious, and that i would say they were irrational.\"[15] He lived out of his automotive, and additionally stayed with friends for many months whereas attendinghighschool. He was awarded a school scholarship and went on to earn 3 degrees at Purdue University.[15]

Rappaport 1st developed associate affinity for radio at age five once he would visit his grandparent, and alongthey\'d pay hours \"tuning around, being attentive to Morse code and ship-to-shore\" on his grandfather\'s Philco antique shortwave radio.[17] From those early beginnings, he developed a fascination for wireless and \"loves to experiment with antennas\".[17] At age fourteen, he broken his leg taking part in soccer that resulted in confinement to a body solid for 6 months. His granny gave him a shortwave radio that helped keep him occupiedwhereas his leg was healing. He noninheritable his ham radio license,[18] and whereas in highschool began teaching adults Morse code. it had been through his ham radio activity that he met the families he lived with whenbeing forced to depart his parent\'s home. He credits those families as \"wonderful role models\".[15] when he graduated highschool, Rappaport sold-out his automotive, boxed-up his belongings and hitchhiked to West Lafayette, American state to attend Purdue. His scholarship did not cowl all the bills therefore he worked aspectjobs, like cleanup up garbage cans within the student residence, acting at the field station, and doing a littleco-op work for Magnavox.[15]

Rappaport was among the primary graduates of Purdue University\'s National Science Foundation Engineering center(ERC) wherever he co-authored the proposal that resulted within the National Science Foundation award conferredto Purdue by President Ronald Wilson Reagan. Rappaport\'s master\'s thesis, that was used for the project, was onshow and garnered some attention from Reagan, United Nations agency told Rappaport, \"Nice job, son.\" it had been at that time Rappaport knew he wished to be an educational.[17] Rappaport met his married person Brendathroughout his sophomore year; she was associate agricultural engineer additionally attending Purdue.[15][17] They married before his senior year at Purdue, and had 3 youngsters along.[15]
