This paper proposes a performance criterion for implementing subsample delay by means of relative delay differences. Considering the characteristics of the USRP X300, the proposed performance criterion is to specify the amplitude value as absolute error and the delay error as relative error for a bandwidth of 80% of the Nyquist frequency. It was also pointed out that using the delay difference between $tau_d=15.75$ and $tau_d=15.8$ is better than using the delay difference between $tau_d=15$ and $tau_d=15.05$ when achieving small relative delay differences such as $0.05$ samples. The reason for this is that the former has similar delay characteristics. |
