| titleOfInvention | Methods and devices for handling channel mismatches of an i/q down-converted signal and a two-channel ti-adc |
| abstract | A method and device for handling an in-phase and quadrature, "l/Q", channel mismatch of an I/Q down-converted signal, and a use of the device. A discrete-time complex valued signal r(n) based on an analog-to-digital conversion of the l/Q down- converted signal is obtained (101). The obtained discrete-time complex valued signal r(n) is oversampled by a factor of two or more. An intermediate signal v(n) is formed (102) from the discrete-time complex valued signal r(n) . The intermediate signal v(n) corresponds to the real part of a π/2 frequency shifted version of the obtained discrete- time complex valued signal r(n). A procedure for obtaining an estimate of a frequency dependent mismatch of a two-channel time-interleaved analog-to-digital converter, "Tl-ADC" is applied (103) on the formed intermediate signal v(n). Thereby a TI-ADC mismatch estimate is obtained. The I/Q channel mismatch is estimated (104) and/or compensated (105) based on the obtained TI-ADC mismatch estimate. This e.g. offers real-signal processing solutions to the complex-signal mismatch estimation and compensation problem for I/Q down converted signals in e.g. zero-IF receivers. |
