摘要

提出了一种基于重复脉宽调制(RPWM)的单射频发射机,作为多输入多输出(MIMO)系统的备选方案。然而,RPWM发射机系统的缺点是需要的天线元件数量是传统MIMO发射机的两倍。然后,我们提出了一种先进的RPWM发射机,与传统的MIMO发射机相比,它需要相同数量的天线元件。我们还验证了与传统MIMO系统相比,所提出的RPWM发射机实现了相似的复用增益。

Switch Control Based Single-RF Transmitter for Multiplexing Gain
A single-RF transmitter based on repetitive pulse width modulation (RPWM) was proposed for an alternative system of multiple-input multiple- output (MIMO) system. However, the RPWM transmitter system has a demerit in view of requiring twice the number of antenna elements than the conventional MIMO transmitter. Then we propose an advanced RPWM transmitter which requires the same number of antenna elements compared to the conventional MIMO transmitter in this paper. We also verify that the proposed RPWM transmitter achieves similar multiplexing gain compared to the conventional MIMO system.
