In this letter, an opportunistic NOMA (ONOMA) scheme is proposed in a coordinated multipoint (CoMP) system. Compared with the conventional joint-transmission (JT) NOMA in CoMP, the main purpose of the ONOMA scheme is to advance the capability of the CoMP system and the effectiveness of the successive-interference-cancellation (SIC) decoding process. The relationship between the topology of the ONOMA...
The non-orthogonal multiple access (NOMA) is regarded as a promising multiple access technique for 5G network. In this research, comparing with the joint transmission (JT) NOMA in Coordinated Multi-Point (CoMP) system, we propose a novel opportunistic NOMA (ONOMA) scheme, which aims to improve the efficiency of the successive interference cancellation (SIC) decoding in conventional NOMA. Besides,...
In the past few years, extensive research has focused its attention on interference alignment (IA) methods that are aimed at improving the interference networks potential. However, the channel state information (CSI) precision has a correlation with the functionality of IA. When the CSI is completely outdated then there is a possibility that performance effectiveness and gain of IA could be lost....
