| 发明名称 | Multi-path detection | ||
| 摘要 | A method for detecting multi-path interference in a spread-spectrum signal. A variation of a first signal and a variation of a second signal is compared. The variation of the first signal corresponds to a correlation of the spread-spectrum signal and a spreading code having a first offset. The variation of the second signal corresponds to a correlation of the spread-spectrum signal and the spreading code having a second offset. Multi-path interference is detected in dependence on the comparison. | ||

| 主权项 | 1. A method for detecting multi-path interference in a spread-spectrum signal comprising: comparing a power variation of a first signal corresponding to a correlation of the spread-spectrum signal and a spreading code having a first offset, and a power variation of a second signal corresponding to a correlation of the spread-spectrum signal and the spreading code having a second offset by calculating a ratio of power variation between the first and second signals; and detecting multi-path interference based upon the comparing by determining whether the calculated ratio of power variation is within a threshold range. | ||
