FEC Ad Hoc Group Activity Update Month 1998 doc.: IEEE 802.11-98/xxx July 2002 FEC Ad Hoc Group Activity Update Lior Ophir Texas Instruments Broadband Communications in Israel Herzlia, Israel lior.ophir@ti.com L. Ophir, Texas Instruments

Summary (as of 7/7/02) Held 3 conference calls One outstanding issue: July 2002 Summary (as of 7/7/02) Held 3 conference calls 11 active participants Minutes can be found in document 02/394r3 One outstanding issue: Error propagation phenomenon of current FEC proposal in OFDM modes Group feels this makes the current FEC proposal broken, and needs to be fixed 4 alternatives mentioned/presented/uploaded No consensus yet… L. Ophir, Texas Instruments

Proposed solutions for FEC problem July 2002 Proposed solutions for FEC problem Dual scrambler solution Presented in the May meeting by Heegard et al., doc. 02/325 Introduce 2 additional known bytes to the MAC header Submission by Ojard, doc. 02/414 Introduce 4 additional known bytes to the MAC header Discussed by Ghosh, doc. ??? Maintain scrambler seed tables Submission by Lewis, doc. 02/415 L. Ophir, Texas Instruments

Recommendation Continue discussion, and July 2002 Recommendation Continue discussion, and Choose between the available alternatives in order to solve FEC problem L. Ophir, Texas Instruments
