Polarisation/Directional Diversity TRIZ Cases
- MU-MIMO Pilot Sending Method Using Spreading Codes
Spreading multiple signature sequences with one code reduces network resource consumption while enabling accurate precoding matrix estimation.
- MIMO Signal Detection via QR Decomposition and Euclidean Distance
A receiver decomposes channel matrices using QR decomposition to estimate transmit signal vectors through iterative candidate selection.
- STBC-OFDM Signal Detection in Time-Variant Channels
A linear equation calculates decision variables to minimize squared Euclidean distance for STBC-OFDM signals.
- VMIMO User Equipment Pairing via Beam Coverage Segmentation
Segments user equipment by beam coverage areas to reduce calculation complexity during VMIMO pairing, avoiding exhaustive search across all unscheduled devices.
- OFDM Symbol Mapping for Bit Error Rate Reduction
Dynamic OFDM symbol mapping places code-related symbols close together in the grid to maintain similar radio channel conditions.
- Adaptive Polarization Control for Wireless Capacity
Adaptive transmission polarization control selects optimal states using minimal feedback resources to maximize downlink capacity.
- Polarization Synthesis Network for Phased Array Antennas
A polarization synthesis network applies complex weights to dual linear polarization elements.
