Frequency-Division Multiplex TRIZ Cases
- Hybrid Circular-Linear Antenna Array for Mobile Beam Steering
A multiplex circular and linear antenna array uses Butler circuits to preserve OAM capacity while adding multi-directional tracking for mobile links.
- Discrete-Time Receiver Filtering for Low-Power Multi-Carrier Demodulation
A sampled discrete-time filter suppresses unwanted subcarriers and finishes demodulation within one symbol to cut receiver power and chip area.
- MIMO-OFDM FFT Scheduling to Cut Operator Count and Delay
A shared FFT/IFFT schedule lets one operator handle MIMO-OFDM symbols across time slots, reducing hardware count and processing delay.
