Abstract:In this paper, non-orthogonal multiple access (NOMA) is studied at downlink under impact of surrounding interference. This study benefits the practical NOMA system since spatially random interference is adopted. More specifically, we consider the antenna selection strategy applied at the base station and compare the performance of two users. By applying a stochastic geometry-based model, homogeneous Poisson point process (PPP) is employed to consider the spatial topology of interference which is located near t… Show more
“…Antenna subset selection at the transmitter and/or receiver has been researched extensively in many kinds of MIMO systems [14][15][16][17][18][19][20][21][22][23][24][25]. It has been employed to improve the performance and reliability over those achievable with wireless communication systems without antenna subset selection.…”
We consider the problem of the efficient transmit antenna subset (TAS) selection for maximizing the signal-to-interference-plus-noise ratio (SINR) of multiuser space–time line code (MU–STLC) systems [...]
