Code Division Multiplex TRIZ Cases
- Hybrid Reference Signal for DFT-s-OFDM
Segments reference signals across subcarriers to improve channel estimation accuracy while preserving power amplifier efficiency.
- DMRS Port Configuration Using FD-OCC for MU-MIMO Capacity
Extended FD-OCC lengths double orthogonal DMRS port counts, enabling higher spatial multiplexing layers in MU-MIMO without increasing reference signal overhead.
- FMCW Radar Waveform Parameter Selection for Multi-Radar Coexistence
A user equipment selects frequency modulated continuous wave parameters to suppress mutual interference between nearby radar sources.
- Dynamic OCC Length Switching for 5G Channel Estimation
A terminal obtains orthogonal cover code length information from control signals to receive reference signals.
- Orthogonal DMRS Port Generation for Pi/2 BPSK
A pi/2 BPSK base sequence generates orthogonal demodulation reference signal ports using frequency-domain comb structures and time-domain orthogonal cover codes.
