Design and realization of wideband IQ imbalance compensation based on blind equalization
In order to solve the wideband IQ imbalance problem, a compensation design based on blind equalization is presented. An improved equalizer design is used in high speed demodulator, which computes IQ imbalance compensation filter by adaptive blind equalization technology, therefore the equalizer has...

| description | In order to solve the wideband IQ imbalance problem, a compensation design based on blind equalization is presented. An improved equalizer design is used in high speed demodulator, which computes IQ imbalance compensation filter by adaptive blind equalization technology, therefore the equalizer has the ability to compensate IQ imbalance and reduce inter symbol interference. In engineering application, this method does not increase additional resource consumption and hardward design complexity. The test result shows this method can compensate IQ imbalance effectively in multiple modulation modes. |
