Subject: Re: [10GMMF] Towards receiver test responses
The attached .xls file contains the candidate TP3 ISI parameters that were requested during the TP3 telecon on 5-Apr-05. The PIE-D targets were generally swept from ~3.5dB to ~5dB, although there will be some variation in the resulting PIE-D due to the nature of the search algorithm.
The results for the split-symmetric response deserve some comment. The first 11 entries in the worksheet are essentially identical. This occurs because split-symmetric responses, as we have defined them, do not exist for PIE-D < ~ 4dB. For PIE-D targets < 4dB, the search algorithm finds the best response possible consistent with the constraints resulting in the same ISI parameters for these cases.
