摘要：

A novel low-complexity optical orthogonal frequency division multiplexing (LCO-OFDM) transmission architecture is proposed in this letter. The LCO-OFDM transmitter consists of two branches, wherein the first and second branches use odd and even subcarriers, respectively. Specifically, only complex multiplications are required in modulated symbols of each branch without Hermitian symmetry and inverse fast Fourier transform operations. Transmission signals of LCO-OFDM can be obtained by transmitting real and imaginary parts of generated complex signals in each branch over two successive orthogonal frequency division multiplexing frames and adding a direct current bias to avoid zero clipping noise. Simulation results showed the optimum performance of LCO-OFDM in terms of both peak-to-average power ratio and bit error rate.
