Decode Modes (6GR)

The per-channel decode modes on the Decode tab select what each physical channel's bit results display. All are auto-coupled — see Auto and Manual Parameter Coupling.

Bit processing runs through six stages: demodulated symbols, demodulated bits, descrambled bits, rate-dematched bits, decoded code block bits, and decoded transport block bits. Each channel's decode mode selects which stage that channel's bit results display; except where noted below, all stages are still processed.

PDSCH Physical Downlink Shared Channel Decode Mode, PUSCH Decode Mode, PDCCH Decode Mode, PUCCH Decode Mode, PBCH Decode Mode - Select the decode mode for each physical channel:

Off (No Bits) - Channel decoding is off; no bits are displayed. Processing stops after demodulated symbols.
Off (Scrambled Bits) - Channel decoding is off; the displayed bits are scrambled bits. Processing stops after demodulated bits.
Descrambled - Channel decoding is on; the displayed bits are descrambled bits.
Rate Dematched - Channel decoding is on; the displayed bits are rate-dematched bits (the output of 3GPP rate de-matching).
Decoded CB - Channel decoding is on; the displayed bits are code block bits.
Decoded TB - Channel decoding is on; the displayed bits are transport block bits.

Default: Off (No Bits) for PDSCH and PUSCH; Off (Scrambled Bits) for PDCCH, PUCCH, and PBCH

Choices: Off (No Bits), Off (Scrambled Bits), Descrambled, Rate Dematched, Decoded CB, Decoded TB
