预编码空间调制（PSM）以其简单的接收机设计和上级误码性能而闻名。为了充分继承其优点并克服其在毫米波混合大规模多输入多输出（mMIMO）系统中的不可行性，提出了一种新的混合PSM（hPSM）。除了类似的数字设计之外，hPSM与PSM的明显不同之处在于它依赖于毫米波mMIMO收发器的模拟部分。此外，与PSM不同，其中相关设计足以限制在单个子载波上，hPSM需要跨所有子载波的联合考虑。由于我们明智的设计，hPSM的错误性能得到优化，并证明是优于其非hPSM对应。同时，整体设计与流行的混合毫米波系统兼容，并具有较低的实现复杂度。
Precoded spatial modulation (PSM) is well-known for its simple receiver design and superior error performance. To fully inherit its advantages and overcome its unfeasibility to mmWave hybrid massive multi-input multi-output (mMIMO) systems, a novel hybrid PSM (hPSM) is carefully proposed. Except for a similar digital design, hPSM distinctly differs from PSM for its dependence on the analog part of the mmWave mMIMO transceivers. Moreover, unlike PSM where the relevant design suffices to be restricted on a single subcarrier, hPSM requires joint consideration across all subcarriers. Thanks to our judicious design, the error performance of hPSM is optimized and demonstrated to be advantageous over its non-hPSM counterpart. Meanwhile, the overall design is compatible with prevalent hybrid mmWave systems and enjoys a low implementation complexity.
