摘要

为了实现空时频传感和通信系统的多分辨率能力，同时降低复杂性和节约资源，提出了一种基于共轭调频频响掩蔽（CFM-FRM）的可配置信道化优化设计方法。采用系数抽取法实现可配置信道化结构，并采用CFM-FRM方法进一步优化结构以降低实现复杂度。仿真结果表明，该结构可以根据实际需要动态选择最优分辨率。对比分析表明，与现有方法相比，CFM-FRM结构所消耗的乘法器数量显著减少。

A low complexity and multi-resolution structure for Space–Time–Frequency sensing and communication system

To achieve multi-resolution capabilities in space–time–frequency sensing and communication systems while minimizing complexity and conserving resources, we proposed a configurable channelized optimization design method based on conjugate frequency modulation frequency response masking (CFM-FRM). The configurable channelized structure is realized by coefficient decimation method, and the structure is further optimized by CFM-FRM method to reduce the implementation complexity. The simulation results show that the structure can dynamically select the optimal resolution according to the actual needs. Comparative analysis shows that compared with the existing methods, the number of multipliers consumed by CFM-FRM structure is significantly reduced.
