Method and apparatus for configuring a frequency dependent I/Q imbalance compensation filter |
| 摘要 |
A method of configuring at least one frequency dependent (FD), in-phase/quadrature (I/Q), imbalance compensation filter within a radio frequency (RF) module is described. The method includes applying an input signal to an input of the RF module, receiving a filtered I-path signal for the RF module and deriving at least one I-path filtering estimate value therefrom, receiving a filtered Q-path signal for the RF module and deriving at least one Q-path filtering estimate value therefrom, and configuring the at least one FD I/Q imbalance compensation filter based at least partly on at least one ratio between the derived I-path and Q-path filtering estimate values. |

1. A method of configuring at least one frequency dependent (FD), in-phase/quadrature (I/Q), imbalance compensation filter within a radio frequency (RF) module, the method comprising:
applying an input signal to an input of the RF module; receiving a filtered I-path signal for the RF module and deriving at least one I-path filtering estimate value therefrom; receiving a filtered Q-path signal for the RF module and deriving at least one Q-path filtering estimate value therefrom; and configuring the at least one FD I/Q imbalance compensation filter based at least partly on at least one ratio between the derived I-path and Q-path filtering estimate values. |
