Abstract

The chirp spreading modulation (CSM) is used as modulation technique for Long Range (LoRa) wireless networks that support internet of things (IoT) systems. However, this transmission scheme is limited in terms of spectral efficiency. Hence, a novel index modulation technique is proposed for CSM wireless communications systems to enhance the spectral efficiency. The proposed scheme is based on using a variety of spreading factors (SFs) in CSM systems in order to convey additional bits. The performance analysis of the proposed scheme is analytically investigated by deriving the symbol error rate. Moreover, the system performance of the proposed scheme may be investigated in terms of symbol error rate (SER) via numerical simulations and its superiority compared to the conventional CSM transmission scheme is shown.
