Question: In UTRA repeater conformance testing, how is the error power for each code calculated in the context of Code Domain Error measurement?
Option 1: As the difference between the peak power of the error vector and the mean power of the reference waveform, expressed in dBm.
Option 2: As the ratio of the error vector power to the mean power of the reference waveform, expressed in dB.
Option 3: By integrating the error vector power over a full frame and comparing it to the peak power of the reference waveform.
Option 4: Through the subtraction of the mean power of the reference waveform from the error vector power, expressed in watts.
Explanation: The correct calculation for error power in each code involves comparing the error vector's influence on a specific code by relating it to the reference signal's average power. This is accurately described as a ratio rather than an absolute difference or integration over time, expressed in decibels (dB) for scalability and ease of comparison.
