GFDM frame design for low-latency industrial networks

This paper proposes a short packet GFDM-based physical (PHY) layer for industrial wireless networks to reduce latency. In our proposed PHY layer, the conventional OFDM scheme used in data field of IEEE 802.11 WLAN standards is replaced by GFDM. The preamble size also reduced from 10 symbols 1 symbol. Furthermore, fields overall structure are optimized terms total number subcarriers and cyclic prefix length. Additionally, noise-free GFDM subjected concatenated channel coding minimize error rate. Through simulation, transmission time about 40 ∼ 72% compared OFDM-based while achieving PER order 10−3. obtained results show that outperforms its counterpart exhibiting lower latency high reliability. performance renders (proposed) suitable adoption development reliability constrained applications. It should be noted simulations presented this express first step direction using achieve low We therefore consider building fully functional based-testbed as part future work.
