  • Patent number: 10999848
    Abstract: The present disclosure relates to a sparse-coded ambient backscatter communication method and a system. According to the sparse-coded ambient backscatter communication method, in an ambient backscatter system including an access point and a plurality of sensor nodes, each sensor node transmits a code word in a non-orthogonal multiple access (NOMA) manner using sparsity of a signal by a duty cycling operation and the access point detects a superimposed signal transmitted in the NOMA manner by an iterative decoding method in which a dyadic channel and intersymbol interference are reflected. The present disclosure may reduce the implementation cost by reducing the number of impedances required to modulate data of a batteryless sensor node in an Internet of Things environment and utilize the dyadic backscatter channel to detect a signal, thereby providing massive connectivity of the access point.
