Abstract
A fast I/Q imbalance compensation algorithm is presented. It is demonstrated through MATLAB simulations that with a few samples an image-to-signal ratio (ISR) lower than -25 dB was achieved. On the basis of digital processing of the received signal, this algorithm is compliant with low-cost and low-complexity wireless receivers because it does not require extra time and resources for calibration. Moreover, its fast convergence allows reaching a high enough image rejection ratio by adapting the compensation weight during the reception of a known preamble such as defined by the IEEE 802.15.4 or the Bluetooth low energy standards.
