Comments:
The following changes provide updated information for section 6.3.3, Comparison of all TPC Modes. This
information will be incorporated into the next revision.
Change Specifics:
*
The occupied bandwidth is defined at the width of the transmitted spectrum taken at the -10 dB
points on the plot of power spectral density. This equates to 1.19 x symbol rate for the CiM-300L
transmit filtering. Minimum carrier spacing depends on the relative power level of adjacent carriers
and the relative symbol rates. The CiM-300L will experience no more than 0.5 dB BER degradation
with two adjacent like modulated carriers spaced at 1.3 times the symbol rate from the desired
receive carrier, and at +10 dBc power each relative to the desired receive carrier.
