Abstract: A new OFDM system with complex coding diversity comprising N subcarriers is proposed. The transmitted data symbols are grouped in complex format: the in-phase side and the quadrature side of the symbols are arranged with N/2 intervals. The system performance can be improvedgreatly by analysis and computer simulation without increasing the transmittingpower.

Key words: OFDM, diversity, EGC
