CPE (MB-OFDM)
Menu Path:
CPE (Common Pilot Error) is the RMS level of the Common Pilot Error trace data minus 1 and expressed as a percentage of an ideal signal. Ideally the Common Pilot Error trace data has a magnitude of one and a phase of zero. The CPE represents the deviation of the Common Pilot Error trace from the ideal and displays how much the MB-OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. burst drifts over time.
