Paper Abstract
A compensation scheme for transmitter (Tx) and receiver (Rx) I/Q imbalance with the interference of carrier frequency
offset for CO-OFDM transmission is demonstrated. It has low over-head using only two specific designed symbols for
Rx side I/Q imbalance and two for that of Tx side, respectively. Rx compensation is performed in time domain after
OFDM frame synchronization and the Tx I/Q imbalance is compensated in frequency domain after channel and phase
estimation. The bit error rate (BER) and Q improvement are evaluated experimentally to demonstrate the effectiveness of
compensation algorithms. This scheme performs better with the increase of OSNR.
