“…This is the case when the harvester harvests energy from simultaneous transmissions, such as two-way relaying or nonorthogonal multiple access, or from co-channel interference [21], [22]. This is also the case when the power beacons proposed in [7] are deployed in several locations to provide power coverage for the whole network such that one portable device may be served by several power beacons or when distributed antenna systems are adopted, similar to [23] but for power transfer.…”

For the poor transmission reliability of data, this paper focuses on the precoding techniques of the multi-user MIMO system in the broadcast phase in, and the single-user MIMO and multi-user MIMO precoding techniques have been studied. In the multi-user MIMO system, BD-MMSE-VP coding algorithm is proposed to improve the BER performance of the system by using the MMSE criterion to optimize the perturbation vector, and the system uses QR technique to decompose BD channel matrix. Simulation results verify the effective of the proposed precoding algorithm.

“…In addition, reducing the unnecessary protection interval between sub-bands through suppressing the out-of-band (OOB) power of in-band data is another effective method to relieve the increasingly scarce spectrum resources. High OOB emission is always the shortcomings of traditional multicarrier schemes and becomes the opposed target of novel waveform candidates of the fifth generation (5G) with multi-antenna [4,5]. For instance, traditional orthogonal frequency division multiplexing (OFDM) system suffers high OOB leakage *Correspondence: meilin@hit.edu.cn 1 Communication Research Center, Harbin Institute of Technology, Harbin, China Full list of author information is available at the end of the article due to slow tailing attenuation of sinc function and needs the protected subcarriers to inhibit OOB power radiation.…”

High out-of-band (OOB) power emission has become the main shortcoming of multicarrier scheme in regard to the requirements and challenges of 5G. In this paper, two effective OOB power reduction methods, previously applied to traditional orthogonal frequency division multiplexing (OFDM) system, are proposed in hybrid carrier (HC) scheme based on weighted-type fractional Fourier transform (WFRFT). Simulation results demonstrate that, due to the flexible selection of WFRFT order in the HC system, combined bit error rate (BER) and peak-to-average power ratio (PAPR) performance advantages are gained without sidelobe impact and significant complexity increase in comparison with the OFDM scheme with spectrum precoding. In projection precoding, a smaller error vector magnitude of precoder G χ is obtained in the proposed hybrid carrier scheme. In SVD precoding with an orthogonal decoding at the receiver, better BER performance could also be acquired at WFRFT order over the fading channels. The proposed two WFRFT-based structures are complementary, and their potential scenarios are given. In addition, applying the feature of projection precoding to channel estimation, a novel pilot structure based on WFRFT is posed to reduce the introduced error of spectrum precoding and finally helps to improve the BER performance.
