| Outline of Final Research Achievements |
Todays, wireless communication systems demand highspeed and highefficient data transmission. Therefore, orthogonal frequency division multiplexing (OFDM) systems have been adopted in a lot ofcommunication standards. Also, the direct-conversion receiver without intermediate frequency hardware components, is small, low-power consumption, and low-cost to equip.
In this paper, we propose a novel blind I/Q imbalance estimation for the direct-conversion OFDM receiver.
