摘要/Abstract

摘要：

色散选择性映射(dispersive selected mapping, DSLM)是降低基于偏移正交幅度调制的滤波器组多载波(filter bank multicarrier with offset quadrature amplitude modulation, FBMC/OQAM)系统峰均比(peak to average power ratio, PAPR)的技术, 但是该方法需要传输额外比特边带信息(side information, SI)。为了抑制FBMC/OQAM系统的PAPR, 提高系统的频谱利用率, 在DSLM的基础上, 提出了一种无边带信息的色散选择性映射(without side information of DSLM, W-DSLM)方法。W-DSLM通过在相位序列中挑选特定的位置, 并插入模值大于1的扩展因子对相位序列进行改进, 然后利用扩展因子与相邻位置的能量差, 在接收端得到最优相位序列, 从而恢复出传输的符号。扩展因子的插入避免了边带信息的传输, 因此能够有效提高系统的频谱效率。仿真结果验证了该方法的有效性。

Abstract:

Dispersive selected mapping (DSLM) is a technique to reduce peak-to-average power ratio (PAPR) of the system of filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM), but this method requires the transmission of additional bitside information (SI). In order to suppress the PAPR of the FBMC/OQAM system and improve the spectrum utilization rate of the system, on the basis of the DSLM, a method without side information for the selective mapping (W-DSLM) is proposed. W-DSLM improves the phase sequence by selecting a specific position in the phase sequence and insert an expansion factor with a modulus greater than one. Then, using the energy difference between the expansion factor and the adjacent position to obtain the optimal phase sequence at the receiver, thus the transmitted symbol is recovered. The insertion of the expansion factor avoids the transmission of sideband information, which can effectively improve the spectrum efficiency of the system. Simulation results verify the effectiveness of this method.

Key words: filter bank multicarrier (FBMC), offset quadrature amplitude modulation (OQAM), peak to average power ratio (PAPR), dispersive selected mapping (DSLM), without side information
