Notice that the power levels have changed on each channel. This process has scaled the
channel power levels to the proper amplitudes for transmission (the sum log value of
the new power levels equals zero). The power ratios between the channels remain
unchanged.
NOTE Adjusting the code domain power applies to active channels only.
9. Toggle the
