A New Frequency-Bin-Index LoRa System for High-Data-Rate Transmission: Design and Performance Analysis

no code implementations29 Mar 2021 Huan Ma, Yi Fang, Guofa Cai, Guojun Han, Yonghui Li

To further improve the system flexibility, we formulate a generalized modulation scheme and propose scheme II by treating the SFB groups as an additional type of transmission entity.

Design and Performance Analysis of a New STBC-MIMO LoRa System

no code implementations28 Jun 2020 Huan Ma, Guofa Cai, Yi Fang, Pingping Chen, Guojun Han

The result demonstrates that the diversity order of the system in the imperfect CSI scenario with fixed channel estimate error variance is zero.
