Wireless Broadband Networks Case Study
The case study involves an in-depth investigation of a wireless
broadband PHY technology and submitting a report (max. 10 pages) on
your research. This page provides a list of suggested topics to help
you decide on a topic. This list is by no means binding. You are free
to come up with a topic of your own. Please make sure that the topic
involves indepth readings (eg: books, survey articles, papers etc). If
the topic you choose has overlaps with materials covered in class, I
will expect that the case study covers far more depth than what is
covered in class. Submit your topic selection, a brief 1-para
description and the list of publications/books that you will go
through in an email to the TA for approval.
Note: you are free to suggest your own topic for inclusion here or for
your case study. If the topic you choose has overlaps with materials
covered in class, I will expect that the case study covers far more
depth than what is covered in class. Each topic is for one student's
study except those explicitly said for 2. If you want to take on a
single-person topic for two people, it should ultimately have
commensurate depth & more breadth; and you should interact with the
professor to determine what "commensurate" means.
- WiMAX: in-depth survey of how concepts like MIMO, OFDM, adaptive modulation/coding, hybrid ARQ, multi-user diversity, scheduling are realized.
- Comparison between HSDPA vs WiMAX vs CDMA 2000 EV-DO Rev A/B
- 3G technologies: in-depth survey of how concepts learnt in class are realized in W-CDMA, CDMA2000 (and their upgrades: HSDPA, EV-DO Rev A/B)
- Space-time coding, MIMO & multiuser MIMO: in-depth survey of advanced concepts
- MC-CDMA: in-depth survey of advanced concepts
- CDMA: in-depth survey of advanced concepts
- Multi-user communications: in-depth survey of advanced concepts (incl. multi-user detection)
- Coding: survey of advanced topics (LDPC, turbo codes, fountain codes).
- Signal processing issues in MIMO and OFDM
- RF Circuits and Chip-design challenges for wireless broadband communications
- Multimedia over wireless networks: VoIP, video streaming/broadcast/multicast over cellular networks, QoS support, Qualcomm MediaFLO, WiMAX MBS services etc
- Cooperative diversity: how diversity gains, MIMO gains are possible by using a cooperating set of nodes.
- Cognitive radio: in-depth survey of state-of-art and challenges
- Software defined radio (SDR): in-depth survey of state-of-art, realization of fundamental concepts, and challenges
- Ultra-wide band (UWB): in-depth survey of state-of-art, realization of fundamental concepts and challenges
- Wireless LAN PHY/MAC: 802.11a/b/g/n
- Wireless meshed networks: PHY/MAC/scheduling issues, IEEE 802.11s, 802.16j
- Bluetooth: in-depth survey of state-of-art, realization of fundamental concepts and challenges
- Zigbee/RFID: in-depth survey of state-of-art, realization of fundamental concepts and challenges
- Spectrum policy for broadband: auctions, beauty contests, current strategies in spectrum allocation for 3G, WiMAX, open-spectrum, UWB etc
The case study is an creative exercise in:
- synthesizing a picture of an area, its relevance, structure and core ideas;
and identifying what problems are worth working on going forward.
- integrating the concepts learnt in class, with an in-depth focus in a single
area.
- understanding the *research* and *engineering* issues in a focus area and
a crisp articulation of state-of-the-art and research/engineering directions
being investigated in the community. No fluff. Suggested length ~ about 10
pages.
- reading key technical research papers, books, survey articles etc.
- If the topic you choose has overlaps with materials covered in
class, I will expect that the case study covers far more depth than
what is covered in class.
- The case study proposal should have:
- List of sub-topics to be covered
- List of papers, books that you plan to read.
- Upto 2 students can collaborate on a case study project, provided the
proposed work is substantial enough (in terms of depth/breadth). Please
refer to course syllabus for due dates.
- The final case study writeup (of about 10 pages) should clearly specify:
- The scope of the problem you are studying - detail all the fundamental
design issues/subproblems involved
- Solution approaches to each of these issues (in isolation)
- Solutions adopted in practice
- Conclusions stating the open issues involved, and possible solution
directions.
- the depth/breadth of issues investigated
- clarity of thought and presentation. Problem definition and scope before
solution presentation.
- quality of critique of the state-of-the-art and insight in presenting open
issues
- If the topic you choose has overlaps with materials covered in
class, I will expect that the case study covers far more depth than
what is covered in class.
- Badly written reports or reports with more "fluff" than
clear technical exposition will lose points in the evaluation.
