Multiplex Code Allocation TRIZ Cases
- Composite CDM-TDM Pilot Signals for Accurate Channel Estimation
Combining CDM pilots with cyclic-prefixed TDM pilots improves channel estimation and preserves orthogonality in complex SFN radio environments.
- UWB Sequence Set Design for Dense Multi-User Ranging
Expanded UWB sequence sets cut inter-user interference in dense scenarios, improving synchronization and ranging across receiver types.
- Symbol Processing for Modulation-Preserving NOMA Transmission
Selected spreading and scrambling sequences preserve π/2 BPSK and π/4 QPSK during RSMA-NOMA transmission for reliable sharing.
