| Abstract: |
| In this paper,a theoretic analysis of weighting signal is made,and the optimum weighting coefficients to silence the less times harmonics in DRFM are derived. The simulation results suggest that the less times harmonics are suppressed efficiently after weighting signals by the optimum weighting coefficients. This provides theoretic foundation and implementation process in engineering to suppress spurious signals. |
