Table 21: Performance Limitations for RESTRICTED Direct PCM Demodulation
Note:
 The performances limitations for QPSK and OQPSK demodulation with NRZ-L/M/S
decoding are significant in the case of separate decoding on I and Q channels for
ambiguities solving too.
 The performances limitations for AQPSK demodulation apply to each Telemetry Unit (I & Q
channels).
