Performance Analysis of a Two-Hop Relaying LoRa System
Wenyang Xu, Guofa Cai, Yi Fang +1
The conventional LoRa system is not able to sustain long-range communication over fading channels. To resolve the challenging issue, this paper investigates a two-hop opportunistic…
A New Frequency-Bin-Index LoRa System for High-Data-Rate Transmission: Design and Performance Analysis
Huan Ma, Yi Fang, Guofa Cai +2
As an attempt to tackle the low-data-rate issue of the conventional LoRa systems, we propose two novel frequency-bin-index (FBI) LoRa schemes. In scheme I, the indices of starting…
Design and Performance Analysis of a New STBC-MIMO LoRa System
Huan Ma, Guofa Cai, Yi Fang +2
LoRa is a modulation technology for low power wide area networks (LPWAN) with enormous potential in 5G era. However, the performance of LoRa system deteriorates seriously in fading…
Design of Link-Selection Strategies for Buffer-Aided DCSK-SWIPT Relay System
Mi Qian, Guofa Cai, Yi Fang +1
Adaptive link selection for buffer-aided relaying can achieve significant performance gain compared with the conventional relaying with fixed transmission criterion. However, most…
Design of an MISO-SWIPT-Aided Code-Index Modulated Multi-Carrier M-DCSK System for e-Health IoT
