Proposed Resolution of D0 Comment S10-417, 418, 515

<J. Kim, C. Lee, H. Lee, S. Choi>, <ETRI>


D0 comment s10 417

D0 Comment S10-417

  • Comment

    • The length 64 for bit interleaving is not sufficient to overcome the burst error

  • Proposed Change

    • Enlarge the length of interleaving

<J. Kim, C. Lee, H. Lee, S. Choi>, <ETRI>


Proposed resolution

Proposed Resolution

  • Discussion

    • Performances

<Interleaver length: 128>

<Interleaver length: 64>

<J. Kim, C. Lee, H. Lee, S. Choi>, <ETRI>


Proposed resolution1

Proposed Resolution

  • Performances

  • Increase the interleaver length to 192

  • <Interleaver length: 384>

    <Interleaver length: 192>

    <J. Kim, C. Lee, H. Lee, S. Choi>, <ETRI>


    D0 comment s10 418

    D0 Comment S10-418

    • Comment

      • The sentence, "This represents the concept of the proposal Group PPM (GPPM)", is declared in draft version 6(15-10-0245-06-0006), but this sentence was eliminated in IEEE802.15.6/D01 for letter ballot.

    • Proposed Change

      • This sentence should be included in the chapter 10.11.3 and the detail explanation are required to insert in the appendix.

    <J. Kim, C. Lee, H. Lee, S. Choi>, <ETRI>


    Proposed resolution2

    Proposed Resolution

    • Discussion

      • In the draft, the name of the non-coherent modulation scheme is not described.

      • Appropriate name of the modulation should be mentioned.

      • Neither OOK and PPM can not express the concept of the modulation in the draft.

    • Add the sentence

      • Page 178, Line 2~4

      • This represents the concept of the Group PPM (GPPM) (see Anex xx)

    • The explanation of the GPPM is required to Annex.

    D0 Comment S10-515

    • Comment

      • Current symbol map GPPM doesn’t appear to be based on some linear code. This will require complex distance decoding at the receiver

    • Proposed Change

      • Replace symbol map by a linear block code

    <J. Kim, C. Lee, H. Lee, S. Choi>, <ETRI>


    Proposed resolution3

    Proposed Resolution

    • Discussion

      • Linear block code

        • All the codewords should be closed in addition

        • To satisfy the criteria, all-zero codeword should be included in codeset

      • For GPPM, 6 ones should be contained in the 12 bit codeword

      • If we use linear block code for the symbol mapping, OOK is employed for the modulation so that it may cause the performance degradation of the system

    • Codeset which which shows the performance enhancement can be accepted, however, linear code cannot be used for the symbol mapper
