More errors and ambiguities in 802.15.4a

Viterbi rate ‘1’ ambiguity Sections 6.8a.8 (Data Field), 6.8a.9 (UWB PHY Modulation) and 6.8a.10 (UWB PHY FEC) all assume that the convolutional code is used. The mapping of the bits in case of the convolutional code is not used (which one goes to polarity, which one to position) is not specified.

Table 39c, PHY Header Thdr Table 39c only list one value of Thdr per PRFmean Each PRFmean can transmit the PHR at 2 rates, either 850 Kb/s or 110 Kb/s Therefore, there should be 2 values for Thdr per PRFmean
