CALIBRATION METHOD FOR WIRELESS COMMUNICATION DEVICE AND ASSOCIATED CALIBRATION APPARATUS |
摘要 |
A calibration method is applied to a wireless communication device having a programmable tuner and a signal processing path. The calibration method includes at least the following steps: configuring the programmable tuner to have a plurality of different tuner states, wherein the signal processing path has a first end and a second end, and the programmable tuner is coupled to the second end; when the programmable tuner is configured to have one of the different tuner states, obtaining a measured reflection coefficient at the first end of the signal processing path; and calibrating mapping relationship between a reflection coefficient at the first end of the signal processing path and a reflection coefficient at the second end of the signal processing path according to the different tuner states and measured reflection coefficients associated with the different tuner states. |

1. A calibration method for a wireless communication device, the wireless communication device comprising a programmable tuner and a signal processing path, the calibration method comprising:
configuring the programmable tuner to have a plurality of different tuner states, wherein the signal processing path has a first end and a second end, and the programmable tuner is coupled to the second end; when the programmable tuner is configured to have one of the different tuner states, obtaining a measured reflection coefficient at the first end of the signal processing path; and calibrating mapping relationship between a reflection coefficient at the first end of the signal processing path and a reflection coefficient at the second end of the signal processing path according to the different tuner states and measured reflection coefficients associated with the different tuner states. |
