MITS5003 Wireless Networks & Communication –
Assignment No 2
Submission Due Date: 04/10/2019 before 5 pm
All submissions are to be submitted through turn-it-in. Drop-boxes linked to turn-it-in will be
set up in the Unit of Study Moodle account. Assignments not submitted through these drop-
boxes will not be considered.
Submissions must be made by the due date and time.
The turn-it-in similarity score will be used in determining the level if any of plagiarism. Turn-it-in
will check conference web-sites, Journal articles, the Web and your own class member
submissions for plagiarism. You can see your turn-it-in similarity score when you submit your
assignment to the appropriate drop-box. If this is a concern you will have a chance to change
your assignment and re-submit. However, re-submission is only allowed prior to the submission
due date and time. After the due date and time have elapsed you cannot make re-submissions
and you will have to live with the similarity score as there will be no chance for changing. Thus,
plan early and submit early to take advantage of this feature. You can make multiple
submissions, but please remember we only see the last submission, and the date and time you
submitted will be taken from that submission.
Your document should be a single word or pdf document containing your report.
1. Convert the binary data “110101” into analog waveforms using following modulation
a. Two level Amplitude Shift Keying
b. Two level Frequency Shift Keying
c. Two level Phase Shift Keying
d. Differential Phase shift keying
e. Four level Amplitude Shift Keying
f. Four level Phase Shift Keying
g. Eight level Amplitude Shift Keying
2. With fc = 1000 kHz, fd = 50 kHz, and M = 16 (L = 4 bits), using Multiple Frequency-Shift
Keying (MFSK), compute the frequency assignments for each of the sixteen possible 4-
bit data combinations.
3. Draw the approximate Analog Modulation and Frequency Modulation waveforms in
complete steps for the following signal:
4. Draw the 16 QAM Constellation Diagram having four different amplitude levels and four
different phase levels.
5. Explain and draw the Error Detection Process for Cyclic Redundancy Check (CRC).
6. Compute the frame check sequence using Cyclic Redundancy Check (CRC) for the
Message = 111010110, Pattern = 101110
7. Compute the transmitted signal using Direct Sequence Spread Spectrum for the
Input: 101, Locally Generated PN bit stream: 011011010110, T = 4Tc
8. Explain why the square and circle shapes cells for cellular communications are not
appropriate as compared to hexagonal shape cells.
