Title
Performance Evaluation Of Ssb Transmission Of Dfts-Ofdm Using Multi-Level Bpsk Through Nonlinear Hpa
Abstract
This paper describes performance evaluation results of SSB (Single Side Band) transmission of DFTs-OFDM (Discrete Fourier Transform Spreading Orthogonal Frequency Division Multiplexing) using multi-level BPSK (Binary Phase Shift Keying) through nonlinear HPA (High Power Amplifier). SSB-DFTs-OFDM is generated by eliminating USB (Upper Side Band) or LSB (Lower Side Band) in frequency domain after DFT spreading of multi-level BPSK signals, thus Hilbert transformer is not necessary to generate SSB signals. The simulation results show that SSB-DFTs-OFDM achieves almost the same PAPR (Peak to Average Power Ratio) and ACLP (adjacent channel power leakage) as conventional DFTs-OFDM and lower PAPR and ACLP than OFDM. Required bandwidth can be reduced by half when BPSK modulation is employed. Furthermore, SSB-DFTs-OFDM using multi-level BPSK shows less error floor and/or E-b/N-0 degradation compared with conventional DFTs-OFDM using QAM modulation in some cases when HPA OBO (Output Back Off) is small. SSB-DFTs-OFDM is an attractive alternative to DFTs-OFDM for WLAN and cellular applications.
