Abstract
Aspects relate to correcting Inphase/Quadrature (I/Q) imbalances across multiple wireless elements such as multiple receive elements or multiple transmit elements. In one example implementation, I/Q imbalances can be corrected using a digital circuit provided within a digital portion of a direct conversion wireless element (upconversion or downconversion) that implements only two multiplications and one addition per pair of I and Q samples.
