This paper studies an uplink simultaneous wireless information and power transfer (SWIPT) system with non-orthogonal multiple access (NOMA), consisting of two users and one energy-harvesting access point (AP). The users transmit their independent information simultaneously to the AP which harvests energy and decodes information at the same time by dynamic power splitting (DPS). We focus on the ergodic...
In this paper, we analyze uplink sum rate of multiple-input multiple-output (MIMO) systems with maximum-ratio combining (MRC) receivers. To be practical, receive correlation and different powers of users are assumed. Two novel approximate results on sum rate are derived in closed form. Based on the results, we also obtain the asymptotic results on sum rate when the number of base station antenna (M)...
This paper investigates the asymptotic behaviour (error and outage probabilities) of a single cell multiple-input multiple-output (MIMO) system aided by a large scale antenna array. Specifically, the uplink transmission over composite fading channel with power-scaling scheme is considered. Where, most reported studies in this respect discuss the case of downlink scenario for convenience MIMO systems...
Distributed multiple-input multiple-output (D-MIMO) is a promising technique for next generation wireless networks, which offers a remarkable spectral efficiency gain over the conventional co-located MIMO (C-MIMO) systems. In contrast to C-MIMO, which can be regarded as a special case of D-MIMO, performance analysis of D-MIMO is a challenging problem. This is because radio channels between a user...
Cyclic delay diversity (CDD) is an attractive diversity technique due to its low complexity and compatibility to existing wireless communication systems. This letter proposes a CDD with frequency domain turbo equalization (FDTE) for single carrier (SC) transmission, in order to achieve the full spatial diversity of frequency-selective multi-antenna channels. The frequency diversity inherent in SC...
