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.
