    • Distortion of a reception signal which is attributable to interference between subcarriers during photoelectric conversion is reduced in an optical OFDM communication system without broadening the signal band. A transmission signal processing unit (100) in a transmitter is provided with a distortion generating circuit (distortion generating unit) (170). A subcarrier signal is utilized as an input signal for the circuit. The distortion generating circuit (170) generates a baseband OFDM signal by means of inverse FFT calculation using the input signal, computes the square of the absolute value of the signal, and restores the subcarrier signal by mean of FFT calculation. Because interference between subcarriers is also included in the signal, the distortion element generated by the interference between the subcarriers can be extracted when the difference from the input signal is found. The signal obtained by subtracting the distortion element from the subcarrier signal, which has been modulated using the original data to be communicated, is used as the transmission signal. The transmission signal is photoelectrically converted with a receiver. The interference between subcarriers generated at this time is smaller than when the aforementioned processing is not performed.
    • 在光OFDM通信系统中减少归因于光电转换期间子载波之间的干扰的接收信号的失真,而不会使信号带宽扩大。 发射机中的发射信号处理单元(100)设置有失真发生电路(失真发生单元)(170)。 副载波信号用作电路的输入信号。 失真发生电路(170)通过使用输入信号的逆FFT计算生成基带OFDM信号,计算信号的绝对值的平方,并且通过FFT计算来恢复副载波信号。 由于子载波之间的干扰也包含在信号中,所以当与输入信号的差异被发现时,可以提取由子载波之间的干扰产生的失真元件。 使用通过使用要传送的原始数据进行了调制的副载波信号中减去失真元件而获得的信号被用作发送信号。 传输信号用接收机进行光电转换。 此时生成的副载波之间的干扰小于不执行上述处理时的干扰。
