A Successive Interference Cancellation Based Random Access Channel Mechanism for Machine-to-Machine Communications in Cellular Internet-of-Things

Energy-Efficient Random Access for Machine- to-Machine (M2M) Communications

In this paper, an average consumed energy for a unit data transmission in analyzed in frequency-agile cognitive radios. The average energy consumed by a random access protocol operated in a channel using a whole system bandwidth is compared with that operated in frequency-separated channels, which results in an energy saving ratio. The energy saving ratio quantitatively evaluates an energy savi...

Successive Interference Cancellation for Interception of the Forward Channel of Cellular CDMA Communications

We develop and evaluate receiver signal processing algorithms for the detection of signals transmitted via the forward link of a cell in a cellular system modeled after the IS-95 standard for direct-sequence spread-spectrum code-division multiple-access (CDMA) communications. Multiuser detectors on board airborne and terrestrial mobile interceptors or monitors attempt the simultaneous detection...

Successive Interference Cancellation Based Signal Detector for Wireless MIMO Communications

Recent Trends in Standards Related to the Internet of Things and Machine-to-Machine Communications

One of major purposes of these standard technologies is to ensure interoperability between entities from different vendors and enable interworking between various technologies. As interoperability and interworking are essential for machine-to-machine communications (M2M) and Internet of Things (IoT) for them to achieve their ultimate goal, i.e., things to be connected each other, multiple stand...

Successive Interference Cancellation in Heterogeneous Cellular Networks

At present, operators address the explosive growth of mobile data demand by densification of the cellular network so as to reduce the transmitter-receiver distance and to achieve higher spectral efficiency. Due to such network densification and the intense proliferation of wireless devices, modern wireless networks are interference-limited, which motivates the use of interference mitigation and...
