| 1 | A Low-Interference Time-Domain N-Continuous OFDM Scheme显示文摘N-continuous orthogonal frequency division multiplexing(NC-OFDM) is an outstanding method to suppress sidelobe for baseband OFDM signals in future 5G wireless communications.However,the precoder of NCOFDM usually causes severe interference and high complexity.To alleviate these problems,this paper proposes an improved time-domain N-continuous OFDM(TD-NC-OFDM) by optimizing the smooth signal,which is the linear combination of rectangularly pulsed OFDM basis signals truncated by a smooth window.Furthermore,we show that the proposed scheme is with lower transceiver complexity and notable performance gain in signal-tointerference-plus-noise ratio(SINR).Lastly,simulation results show that the proposed low-interference TD-NC-OFDM can achieve similar sidelobe suppression performance,with negligible bit-error rate(BER) degradation,compared to conventional NC-OFDM. | Peng Wei Lilin Dan Yue Xiao Xia Lei Shaoqian Li | 2016 | China Communications2016，13，S2： | 3 |
| 2 | Performance analysis of peak cancellation in OFDM systems显示文摘Peak cancellation is a class of peak-to-average power ratio (PAPR) reduction techniques for orthogo-nal frequency division multiplexing (OFDM).It can control the PAPR and out-of-band radiation simultaneously at the cost of additional interference.In this paper,the interference of peak cancellation is modeled and an-alyzed so as to evaluate the degradation of system performance.Furthermore,through theoretical analysis,a closed form of the BER performance is derived for OFDM with popular modulation schemes such as QPSK and 16QAM.Finally,the analytical results are verified by simulations. | XIAO Yue BAI WenLing DAN LiLin WU Gang LI ShaoQian | 2012 | Science China(Information Sciences)2012，55，4： | 2 |
| 3 | A low-complexity multiple signal representation scheme in downlink OFDM-CDMA显示文摘OFDM-CDMA is an attractive technique for broadband wireless communication. However, the high peakto-average power ratio (PAPR) of the downlink signals, generated from multiple spread codes, remains a serious problem. In this paper, a low-complexity multiple signal representation (MSR) scheme is proposed to control the PAPR problem in downlink OFDM-CDMA systems. The proposed scheme generates multiple candidate signals by a novel user grouping scheme, which is without distortion and can provide more PAPR reduction than the conventional MSR schemes, such as partial transmit sequence (PTS) and selective mapping (SLM). Furthermore, a low-complexity processing structure is developed using a novel joint spreading and inverse fast Fourier transform (S-IFFT) to simplify the generation of multiple candidate signals. Complexity analysis and numerical results show that the OFDM-CDMA systems employing the proposed scheme have better tradeoff between PAPR reduction and computational complexity, compared with the conventional MSR schemes. | DAN LiLin XIAO Yue CHENG Peng WU Gang LI ShaoQian | 2009 | Science in China(Series F)2009，52，12： | 1 |

| 6 | Joint Optimization of Peak-to-Average Power Ratio and Spectral Leakage in 5G Multicarrier Waveforms显示文摘High peak-to-average-power ratio(PAPR) and spectral leakage are two main drawbacks of multicarrier systems, such as in orthogonal frequency division multiplexing(OFDM), in future 5G wireless communications. For generating optimized wave forms for 5G communications, this paper proposes an iterative scheme combining time-domain N-continuous OFDM(TD-NC-OFDM) and serial peak cancellation(SPC). Based on the theory of projection onto convex sets(POCS), the effectiveness of the proposed scheme is proved, and the optimized time-frequency domain multicarrier waveforms are analyzed in terms of a balanced tradeoff between out-of-band spectral leakage and PAPR. Both theoretical analysis and simulation results show that the proposed scheme can jointly optimize both the PAPR and out-ofband radiation, with moderate computational complexity. | WEI Peng DAN Lilin ZHOU Cheng XIAO Yue WU Gang LI Shaoqian | 2015 | China Communications2015，12，S1： | 0 |
