The novel FTN detector effectively removes inter-symbol interference (ISI) and viably achieves higher spectral efficiency without needing more bandwidth or power.
About
The exponential growth of wireless devices coupled with emerging technologies like augmented reality and holographic communications demand high data transmission rates as well as costly bandwidth. Faster-than-Nyquist (FTN) signaling, the transmission of pulses beyond the classical Nyquist rate, can be achieved but introduces inter-symbol interference (ISI) that must be removed at the receiver to avoid errors. Existing FTN signaling detection techniques are not practical due to their prohibitive complexity - particularly with advanced modulation techniques – such as high/ultra order quadrature-amplitude modulation (QAM).
This novel FTN signaling detector is designed for ultra-high-order QAM. By exploiting an alternating directions multiplier method, it effectively removes ISI and reconstructs transmitted data symbols with minimal computational effort compared to existing detectors. It viably achieves higher spectral efficiency without needing more bandwidth or power, and without increasing bit errors.
