3.1Agenda

Address parts of motion made in May meeting requiring some results for June 29th.

3.2Notes

Steve: Went over spreadsheet (07-250-01.xls, on reflector) with results for LDPC and CC with blocksizes agreed upon. Simulation conditions for CC and LDPC were the same.

Gerald: Made a comment that is would be nice to see the sameMCS for 1728, as in 384 (Rate ½, QPSK).

John: Suggested that if another simulation should be made it should include the largest blocksize supported for each advanced code.

Changlong: Block size should be used in the table. Block size should also be used often.

Steve: Suggested achart that shows values of SNRfor hitting .1 FER for various block sizes.

Steve: Suggested the importance of having CC simulations also for the blocksizes in the motion. Same simulation conditions, as defined in the motion.

John: Propose to show largest/best block size supported in the coding scheme. It was agreed to include this additional simulation for each advanced coding scheme by the 29th of June, with the following conditions:

Channel B, Rate= ½, QPSK, DS, Spreading the block in the Frequency domain. 802.16 interleaving

Changlong: STBC Goes upto (64, 57) Hamming Code.

Steve: Asked how SNR is calculated in simulations. FT will get back on that.

Gerald: Went over 190-02.xls once again to clarify that 60 sub-channels are used in the downlink.

John: Made comment that all the valid blocksizes shown in the Downstream-60 is the exhaustive set (includes uplink block sizes with linear allocation).
