本文提出了一种毫米波/亚太赫兹频段的无合成器相干接收机，通过混合信号Kramers-Kronig过程重建相位信息，避免了传统高频合成和收发同步的高功耗需求。该接收机适用于资源受限环境下的低延迟通信、传感和成像应用。
in the high mmWave and sub-THz frequencies can enable new applications in communication, sensing and imaging, if they can operate with low latency in high resource-constrained environments. In particular, for one-to-many network nodes where the receivers can be highly energy-limited, processing traditional spectrally-efficient signals that utilize both amplitude and phase modulation (e.g., QPSK, 16/64-QAM etc.) places a significant power burden on highfidelity frequency and phase synthesis, and Tx-to-Rx synchronization at the receiver (Rx) [1,2]. For such coherent communication, the Rx needs to implement its own phaselocked loop with integer/fractional frequency synthesis, carrier recovery and synchronization, and subsequent phase alignment. At high frequencies, the strict power and latency requirements for such complex synchronization make many critical low
