| Research Abstract |
In direct-conversion receivers(DCR), I/Q imbalance has been known as a major analog impairment. This project focuses on the joint compensation of CFO and I/Q imbalance in low-cost OFDM/MIMO-OFDM DCR. A low-complexity compensation algorithm and the associated generalized periodic pilot have been proposed. Furthermore, the propose compensation algorithm has been extended to work with the conventional periodic pilot in the existing wireless standard.
