3 terminology and units of measurement
Peak code domain error (PCDE).
The error vector power by mapping to a specific spreading factor code domain, code domain error on each codeword is the codeword
Mapping the average power and the complex plane reference waveforms to average power ratio, and expressed in dB. Peak code domain error is that all code
Code domain error word in the maximum. The measurement interval is one timeslot.
4 Overview
