NOTE – When additional spectrum shaping is used as described in clause 6 (for example, to provide spectrum
compatibility or to comply with wideband power limit), various parts of the TxPSDM could be reduced by switching
subcarriers off or reducing their transmit power. Additional frequency notches may also be applied if required.
7.2.1.2 Out-of-band LPM
The out-of-band LPM shall be as shown in Figure 7-3 for the low-frequency edge, and in Figure 7-4 for the
high-frequency edge, where PSDtr1 is the value of the in-band LPM at frequency ftr1 and PSDtr2 is the value of
the in-band LPM at frequency ftr2. The parameters for these LPMs are presented in Tables 7-4 and 7-5,
respectively.
The out-of-band LPM applies for frequencies below the low-edge transition frequency ftr1 and for
frequencies above the high-edge transition frequency ftr2. The PSD values between the transition
frequencies ftr1 and ftr2 are considered as in-band and defined in clause 7.2.1.1.
