【摘要】 未来无线通信最富挑战和最重要的问题之一是无线和移动手持设备的功率消耗问题。为了解决终端能量消耗过快增长的问题,同时保证系统信噪比不变,提出利用多维球形星座设计来代替立方平面的星座映射。仿真结果证明,多维球形星座设计在提高系统抗干扰的同时也降低了能耗。更多还原

【Abstract】 One of the most challenging and important topics for future wireless communications is the power consumption of wireless and mobile handheld devices. In order to solve the problem of terminal power consumption growth and keep the system SNR unchanged,multi-dimensional spherical constellation mapping is proposed to replace cube constellation mapping. The simulation results show that multi-dimensional spherical constellation mapping can reduce terminal power consumption and also improve the ability of resisting interference.更多还原
