IEEE 802.16 Tutorial Presentations

802.16 has two sorts of tutorial presentations:
  1. 802 Tutorials at 802 LMSC Plenary Sessions
  2. Open Forum Tutorials at 802.16 Interim Meetings

802 Tutorials at LMSC Plenary Sessions

At IEEE 802 LMSC Plenary Sessions, tutorials are normally scheduled on Monday and Tuesday evenings from 6:30 - 8:00 and 8:00 - 9:30 pm.

The tutorial rules are explained in the 802 Chair's Tutorial Guidelines (part of the IEEE 802 LMSC Guidelines).

To propose a tutorial, submit the IEEE 802 LMSC Official Tutorial Request Form to the Working Group Chair with a request that the proposal be forwarded to the 802 Executive Committee.

Slides of previous 802 tutorials are cataloged on the 802 tutorial page.

Open Forum Tutorials at 802.16 Interim Meetings

The 802.16 Tutorial Open Forum is an opportunity to present detailed explanations of issues that are related to existing or proposed 802.16 projects but are not responsive to any specific Call for Contributions. Talks are to be educational, not commercial.

Presentation Materials
Presentation materials must follow the rules of the 802.16 Presentation Cover Sheet. In particular, logos and other unnecessary commercial graphics are not permitted. The 802.16 Presentation Cover Sheet is required if the authors intend to submit the material for posting to the web.

To have a presentation scheduled on the agenda, request a specific amount of time from the 802.16 Chair. Include with your request a title and an abstract. Also submit presentation slides, if available. The Chair intends to fulfil requests on a first-come, first served basis. However, the Chair may choose to limit the duration of presentations based on allowable time. The Chair may also refuse presentations on grounds of overly commercial content.

Announcement of Agenda
802.16 will notify session attendees of the Tutorial Open Forum agenda so that they may chose which presentations to attend.

Participation Credit
The Tutorial Open Forum is not an official 802.16 meeting. Attendance will not be recorded.

Session #18 Tutorial: 12 March 2002
802.16 MAC Layer Mesh Extensions Overview
Dave Beyer, Carl Eklund, Mika Kasslin, and Nico van Waes

Session #11, Open Forum Tutorial #1: 22 January 2001, 7:00-8:00 pm
Frequency Domain Equalization for 2-11 GHz Broadband Wireless Systems
David Falconer
Dept. of Systems and Computer Engineering
Carleton University

Lek Ariyavisitakul
Broadband Wireless Solutions

Broadband wireless systems deployed in outdoor non-line of sight environments may encounter delay spreads of over 5 to 10 _s - which can cause potential intersymbol interference over 50 or more data symbol intervals. OFDM (orthogonal frequency division multiplexing) has been suggested to combat this ISI problem with reasonable complexity. However OFDM systems generate high transmitted peak-to-average ratios and are sensitive to phase noise; this can increase RF subsystem cost and complexity.

In this tutorial we survey recent advances in frequency domain equalization (FDE) for single carrier (SC) systems. SC modulation systems have lower peak-to average-ratios than OFDM, and when combined with FDE, their performance is at least as good as OFDM systems (in some cases better); furthermore, they have the same reduced signal processing complexity enjoyed by OFDM systems.

We introduce linear and decision feedback equalization versions of SC-FDE, and present some comparative performance results. We briefly explore the possible interoperability of OFDM and SC-FDE systems, and also present a proposal for reducing subscriber unit cost and complexity by employing OFDM in the downlink and SC-FDE in the uplink.

Session #7, Open Forum Tutorial #1: 1 May 2000, 7:00-8:00 pm
Turbo Product Code Tutorial
Dave Williams, Advanced Hardware Architectures

In this tutorial, I cover basic theory of turbo codes comparing various FEC technologies including Reed-Solomon, convolutional codes, Turbo Convolutional Codes, and Turbo Product Codes. I also compare TPCs against TCM concatenated with Reed-Solomon coding.

The tutorial also covers the use of TPCs with higher order modulation such as QAM and m-ary PSK for the purpose of bandwidth reduction. Other topics include burst error correction, tradeoffs between block size, code rates and soft decision resolution.

In its entirety, this tutorial will take 90 minutes, including time for audience interaction, questions, and discussion.

Session #7, Open Forum Tutorial #2: 2 May 2000, 8:30-10:00 pm
Coded Orthogonal Frequency Division Multiple Access
Zion Hadad, Runcom Ltd.

In this tutorial I shell discuss the Coded Orthogonal Frequency Division Multiple Access (COFDMA) technique. The tutorial will contain explanation on the OFDM basics and coverage options, including Single Frequency Network (SFN) and its possible application for fixed and mobile applications. I discuss several possible coding and multiplexing implementations, including scenarios for multiple access and bandwidth on demand allocations. I also present a newly innovative approach for multiple access allocation using Reed Solomon series, which allows a better Carrier Allocation.

Session #5 Open Forum Tutorial: 13 January 2000

Moshe Ran, TelesciCOM Ltd.
