Simultaneous wireless information and power transfer is considered for multi-group multicasting OFDM systems. Each user has the energy harvesting capability through a power splitter (PS). The power and subcarrier allocation at the base station is done such that the minimum signal-to-noise ratio among the users for each subcarrier is maximized while user needs for harvested power are satisfied. The optimization of PS ratios in addition to resource allocation is realized in a joint manner. It is shown that the problem can be cast in a convex optimization form for the given subcarrier sets. In order to determine the subcarrier sets, an efficient subcarrier allocation algorithm is proposed. It is shown that the proposed method performs very close to the exhaustive search, which gives the optimum solution.

Max-Min Fair Precoder Design and Power Allocation for MU-MIMO NOMA Yalcin, Ahmet Zahid; Cetin, Mustafa Kagan; Yüksel Turgut, Ayşe Melda (2021-06-01) In this correspondence, transmit precoders and their power allocation coefficients are designed jointly for a downlink non-orthogonal multiple access (NOMA) wireless communication system. The objective is to provide max-min fairness (MMF) among the strongest users in each group, while maintaining minimum target rates for all the other users. The proposed solutions are respectively based on semi-definite relaxation (SDR) and successive convex approximation (SCA) and on the minimum mean square error (MMSE) ap...
Concurrent operation of wireless power transfer based contactless slip ring and motor drive system with a single converter Ayaz, Enes; Keysan, Ozan; Department of Electrical and Electronics Engineering (2022-9) This thesis presents a novel approach for concurrent power transfer to wired and wireless systems using a single inverter. This proposed approach fits a cost-effective solution to wireless power transfer (WPT) systems used in contactless slip rings (CSR) applications such as sensors, radars, or wind-turbine pitch controls. In conventional systems, there are two separate converters: one is for the motor drive, and the other is for the WPT system. It is proposed that the switching harmonics of the motor drive...
MULTI-GROUP MULTICAST BEAMFORMING FOR SIMULTANEOUS WIRELESS INFORMATION AND POWER TRANSFER Demir, Özlem Tuğfe; Tuncer, Temel Engin (2015-09-04) In this paper, simultaneous wireless information and power transfer (SWIPT) concept is introduced for multi group multicast beamforming. Each user has a single antenna and a power splitter which divides the radio frequency (RF) signal into two for both information decoding and energy harvesting. The aim is to minimize the total transmission power at the base station while satisfying both signal-to-interference-plus- noise-ratio (SINR) and harvested power constraints at each user. Unlike unicast and certain ...
SWIPT for Max-Min Fair Multi-Group Multicast Beamforming Through Power Splitting Demir, Özlem Tuğfe; Tuncer, Temel Engin (2017-03-22) In this paper, simultaneous wireless information and power transfer (SWIPT) is considered in the context of multi-group multicast beamforming. A base station transmits more than one multicast streams to the groups of users where each group targets its own information signal. Users have single antenna and the received radio frequency (RF) signals are split into two for both information decoding and energy harvesting through a power splitter device. The aim is to maximize the minimum signal-to-interference-pl...
High Order QAM Performance Under Phase and Amplitude Distortions Gulgun, Ziya; Yılmaz, Ali Özgür (2018-07-11) High Order QAM such as 512QAM, 1024QAM along with mm-wave transmission is one of the strong candidates for next generation wireless networks. However, due to nonlinearities of RF devices the performance of higher order QAM may be hampered and restrict the transmission rate. As observed in many studies in the literature, outermost constellation points are usually more adversely affected by these impairments. In our previous work, we analyzed this effect by using the Rapp model. Namely, only amplitude distort...
