Diversity/Multi-Antenna Systems TRIZ Cases

Dual trailer and vehicle antennas adjust Wi-Fi phase shifts to keep video clear when trailer geometry blocks line-of-sight.

Offset feed antennas on a dual-reflector OTA setup extend frequency coverage while keeping the quiet zone centered and avoiding extra positioners.

Integrated demultiplexor routing switches a transmitter output between antennas without on-board switches, cutting pin use, cost, and complexity.

Training-sequence correlation lets a UE distinguish VAMOS from non-VAMOS signals and switch receivers accurately during DTX and power imbalance.

Sigma-delta 1-bit IQ modulation with low-order analog filtering cuts transmitter power while preserving link quality and spectral mask compliance.

A single switched channel handles I and Q signals to reject image interference while cutting receiver area and power use.

Joint encoding of beam resources and transmission parameters cuts MIMO signaling overhead while preserving flexible transport block sizes.

A secondary Bluetooth or WAN link sets beamforming for a 60 GHz proxy, enabling compact devices to handle multiple wireless standards.

Creates a de-correlated MIMO channel from one transmit antenna, reducing mobile-station and protocol complexity while partially nulling interference.

Cyclic shifts and unitary mixing expand K data streams across more antennas, boosting receiver sensitivity without extra beamforming circuitry.

Optimized transmitter and receiver weights create beam nulls and equalize stream SNRs, reducing MIMO interference and distortion.
