METHOD AND APPARATUS FOR PROVIDING AN ENHANCED ZERO-IF RECEIVER ARCHITECTURE FOR A WIRELESS COMMUNICATIONS SYSTEM |
摘要 |
<p>An approach includes injecting a plurality of equal amplitude tones across a frequency band. The approach also includes determining frequency response based on the injected tones, determining an imbalance parameter associated with a quadrature down-converter based on the determined frequency response; determining one or more parameters for wideband quadrature compensation based on the determined frequency response, and compensating an input signal based on the determined imbalance parameter and the determined one or more parameters for the wideband quadrature compensation.</p> |
