Practical Channel Splicing using OFDM Waveforms for Joint Communication and Sensing in the IoT
Sigrid Dimce, Anatolij Zubow, Alireza Bayesteh +2
Channel splicing is a rather new and very promising concept. It allows to realize a wideband channel sounder by combining multiple narrow-band measurements. Among others, channel s…
Unsourced Random Access with ThresholdBased Feedback
Murwan Bashir, Ehsan Nassaji, Dmitri Truhachev +2
In this paper we focus on a feedback mechanism for unsourced random access (URA) communications. We propose an algorithm to construct feedback packets broadcasted to the users by t…
Towards the Standardization of Non-orthogonal Multiple Access for Next Generation Wireless Networks
Yan Chen, Alireza Bayesteh, Yiqun Wu +13
Non-orthogonal multiple access (NoMA) as an efficient way of radio resource sharing can root back to the network information theory. For generations of wireless communication syste…
SCMA for Open-Loop Joint Transmission CoMP
Usa Vilaipornsawai, Hosein Nikopour, Alireza Bayesteh +1
Sparse Code Multiple Access (SCMA), a non-orthogonal multiple access scheme, has been introduced as a key 5G technology to improve spectral efficiency. In this work, we propose SCM…
SCMA Codebook Design
Mahmoud Taherzadeh, Hosein Nikopour, Alireza Bayesteh +1
Multicarrier CDMA is a multiple access scheme in which modulated QAM symbols are spread over OFDMA tones by using a generally complex spreading sequence. Effectively, a QAM symbol…
Uplink Contention Based SCMA for 5G Radio Access
Kelvin Au, Liqing Zhang, Hosein Nikopour +5
Fifth generation (5G) wireless networks are expected to support very diverse applications and terminals. Massive connectivity with a large number of devices is an important require…
