| 摘要 |
The invention is a repeater for a telecommunications transmission syste m such as a CDMA wireless system. The repeater reduces leakage by means of a feedback signal whose amplitude and phase are adjusted in response to the amplitude a nd phase of a sampled input signal when a switch turns off the normal output of the repeater for a short period of time. In one embodiment, a pilot signal is transmitted durin g this time period so that the sampled input is the leakage signal. In another embodimen t, the sampled input is the normal transmission signal received during the time period.
