Performance analysis of compressed sensing based multi-user detection technique in small packet transmission scenario

摘要

Massive machine type communication (mMTC) will become the key factor of the future industrial automation area. Also, with the rapid development of Internet of Things (IoT) technologies, more and more researchers in industries and universities have engaged in exploring the problems in mMTC. Currently, one attractive problem is how to cope the requirement of massive connections. One powerful candidate technique to tackle this problem is the Compressive Sensing based Multi-User Detection (CS-MUD) which exploit the sparsity characteristic of the small packet transmission. In this paper, we will perform the performance evaluations with different cases. The simulation results inspire us that in order to fully utilize CS-MUD, the industrial applications should judiciously set the mMTC parameters according to the property of their own business demand.
