VDES signal direct up-conversion design
Sheng Xu, Jianxin Wang, Shushu Yang · 2025
Based on VDES, a scheme for VDES signal direct up-conversion and interpolation filtering is proposed. The shaped filtered VDES signal undergoes multi-stage interpolation filtering and digital up-conversion before transmission. In the process of multi-stage interpolation filtering, a cascade design of Cascaded Integrator-Comb (CIC) filters and Half-Band (HB) filters is employed to reduce resource consumption.
