Backscatter Communication (BackCom) is a low-power communication technique used in the Internet of Things (IoT) technologies. It involves connected devices reflecting and modulating existing signals by altering their load impedance, rather than generating signals themselves5. This method allows for efficient data transmission with minimal energy consumption, making it ideal for IoT applications.
BackCom contributes to IoT adoption by providing a low-power communication method for IoT devices. It allows devices to reflect and modulate existing signals instead of generating signals themselves, reducing power consumption and enabling longer battery life. This makes it an attractive solution for applications that require energy efficiency and long-lasting device operation.
Higher-order modulation like QAM (Quadrature Amplitude Modulation) offers several advantages in communication systems1. It allows for the transmission of multiple bits of data simultaneously, resulting in higher data rates1. QAM also provides greater spectral efficiency, enabling more information to be transmitted within the same bandwidth. Additionally, QAM exhibits robustness to noise and interference, making it suitable for various communication applications, including wireless and satellite communications.
