“…Considering the multi‐scenarios and multi‐requirements in 5G communication scheme, combined multi‐object optimisation plays an important role in designing balanced system with flexible performance. WFRFT as a precoding technique meets these requirements perfectly and the compatibility in many communication schemes has been proven in [8–12, 18–21].…”

“…Compared to the results at

β = 0

, the out of band power is significantly reduced through pulse shaping in frequency domain after 0.7‐order WFRFT and the input signal is reckoned in fractional domain. Furthermore, the out of band power radiation performance is unrelated with the WFRFT orders due to the unitarity of WFRFT proven in [21], so the out of band power results at other WFRFT orders can also be expected and obtained.…”

“…However, a joint PAPR and sidelobe reduction method is put forward in [30], which proves the feasibility in the HC system. Considering the strong compatibility of the HC system, we could combine spectrum precoding with PAPR suppression to achieve a joint suppression in future work.…”

“…3 could achieve different WFRFT precoding orders of data and pilot. Nevertheless, the out-of-band power suppression performance remains unchanged due to irrelevance between OOB and WFRFT order proven in (30). As given in (22), a relatively optimal WFRFT order α could be picked out according to the spectrum precoding G. Considering this principle, the pilot precoderĜ p in (42) is processed by β order WFRFT, expressed as…”

“…In [29], the ICI coefficients introduced by carrier frequency offset is derived in the HC system according to the conclusions in the OFDM and SC systems. In [30], the joint PAPR and sidelobe reduction is achieved in the HC scheme via time domain windowing and frequency domain pulse shaping, where the WFRFT order is proven to be a beneficial regulation of PAPR and BER.…”

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.
