INTERFERENCE MITIGATION FOR POSITIONING SYSTEMS |
| 摘要 |
An interference removal filter that includes a combination of a first filter and a second filter, where the first filter passes signals over a frequency range of size B with a variation of less than +/−3 dB, where the peak value of the impulse response of the second filter is displaced in time from the peak value of the impulse response of the first filter by at least 2/B time units, and where the combination of the first filter and the second filter produces a notch in frequency at a frequency location within the frequency range. |

1. An interference removal filter comprising:
a combination of a first filter and a second filter, wherein the first filter passes signals over a frequency range of size B with a variation of less than +/−3 dB, wherein the peak value of the impulse response of the first filter and the peak value of the impulse response of the second filter are displaced in time from one another by at least 2/B time units, and wherein the combination of the first filter and the second filter produces a notch in frequency at a frequency value within the frequency range. |
