This paper is focused on code-domain non-orthogonal multiple access (CD-NOMA), which
is an emerging paradigm to support massive connectivity for future machine-type wireless …

The non-orthogonal multiple access (NOMA) allows one subcarrier to be allocated to more
than one user at the same time in an orthogonal frequency division multiplexing (OFDM) …

This paper is concerned with a uplink scheme for multicell large antenna systems. We study
a channel estimation technique where partially decoded data is used to estimate the …

This paper provides an overview on the rationales in incorporating massive multiple-input
multiple-output (MIMO), non-orthogonal multiple access (NOMA), and interleave division …

This paper is concerned with pilot transmission schemes in a large antenna system with non-
orthogonal multiple-access (NOMA). We investigate two pilot structures-orthogonal pilot …

In non-orthogonal multiple access (NOMA), signals of different users are independently
encoded and modulated, then superposed in the power domain before transmission. The …

This paper concerns with efficient communication over Gaussian and fading multiple-access
channels (MACs). Existing orthogonal multiple-access (OMA) and power-domain …

The non-orthogonal multiple access (NOMA) technique is considered as a key component
for the next generation cellular system. In downlink NOMA, the constellation of several users …

Non-orthogonal multiple access (NOMA) is one of the potential candidates for future radio
access to address the increasing demands of mobile traffic. NOMA-based systems employ …

This paper deals with the clip** method used in orthogonal frequency-division
multiplexing (OFDM) systems to reduce the peak-to-average power ratio (PAPR). An …
