Question: In the calculation of Peak Code Domain Error (PCDE), what is the primary purpose of descrambling the error vectors in relation to the orthogonal vectors of the channelisation-code set?
Option 1: To align the error vectors with the code space for meaningful inner product calculations, enabling identification of specific code errors.
Option 2: To amplify the error signals for increased sensitivity in detection.
Option 3: To normalize the error vectors by the spreading factor (sf) for consistency across different codes.
Option 4: To convert the error vectors into a format compatible with RMS value calculations.
Explanation: Descrambling the error vectors is crucial for aligning them with the orthogonal vectors of the channelisation-code set, allowing for accurate inner product calculations. This ensures that subsequent analysis can effectively identify and quantify errors associated with specific codes within the code space.
