里德堡原子量子接收机（RAQR）具有高灵敏度和宽可调性，但基于幅度的读出会产生非线性模型，与传统复值多输入多输出（MIMO）处理不兼容。我们针对点对点RAQR辅助的MIMO链路提出一种低复杂度空时编码框架，采用实正交设计对数据符号进行编码，强参考外差接收产生等效实值线性模型，保留的正交性支持匹配滤波逐符号检测，无需矩阵求逆或向量搜索。推导了解析误码率表达式，证明该方案可实现完整的收发分集，仿真验证了分析结果，且相比空间复用基准具有更优性能。
英文摘要
Rydberg atomic quantum receivers (RAQRs) offer high sensitivity and wide tunability, but their magnitude-based readout yields a nonlinear model incompatible with conventional complex-valued multi-input multi-output (MIMO) processing. We propose a low-complexity space-time coding framework for point-to-point RAQR-assisted MIMO links. Data symbols are encoded using real orthogonal designs, while strong-reference heterodyne reception yields an equivalent real-valued linear model. The preserved orthogonality enables matched filter symbol-wise detection without matrix inversion or vector search. An analytical bit error probability expression is derived, proving the proposed scheme achieves the full transmit-receive diversity. Simulations validate the analysis and demonstrate improved performance over spatial multiplexing benchmarks.
