Title
Ultra-Multi-Amplitude-Level Bpsk Based Ssb-Dfts-Ofdm To Achieve Higher Spectrum Efficiency
Abstract
Ultra multi-level modulation such as 1024/4096QAM can achieve higher spectrum efficiency of 10/12 bit/s/Hz than 8 bit/s/Hz achieved by 256QAM in current WLAN/LTE standards, however BER (Bit Error Rate) performance is significantly degraded due to very small reference phase error for coherent detection. This paper proposes ultramulti-amplitude-level BPSK (Binary Phase Shift Keying) based SSB-DFTs-OFDM (Single Side Band Discrete Fourier Transform spreading Orthogonal Frequency Division Multiplexing) to achieve higher spectrum efficiency. Theoretical analysis and computer simulation results reveal the proposed multiamplitude-level BPSK based SSB-DFTs-OFDM is more robust to reference phase error for coherent detection, and lower PAPR (Peak to Average Power Ratio) than conventional 1024/4096QAM.
