Massive machine-type communication (MMTC) is the key technology to meet the flourishing Internet of things industry. One prominent characteristic of MMTC is massive connections which brings a critical challenge of multiple access interference (MAI) on channel estimation, user identification, and data detection. Currently, various techniques have been proposed to mitigate the MAI, but those MAI alleviations...
Non-orthogonal multiple access (NOMA) is a promising candidate for future 5G multiple access. Particularly NOMA uses power domain for multiple access and successive interference canceler (SIC) algorithm for multiuser detection (MUD). Different from the current downlink transmission scheme for NOMA, a novel joint coding scheme is proposed in this paper and corresponding improved SIC algorithms: zigzag...
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...
With the explosive development in Internet of Things (IoT) and Internet of Vehicles (IoV) technologies, massive connections with sporadic transmission will commonly exist in the future communication network. Upon that, compressive sensing based multi-user detection (CS-MUD) technique was proposed in previous works. However, CS-MUD has not been considered in high mobility scenario which will be widely...
