OPTICAL TRANSMITTER, OPTICAL RECEIVER, OPTICAL TRANSMISSION SYSTEM, OPTICAL TRANSMITTING METHOD, OPTICAL RECEIVING METHOD AND OPTICAL TRANSMISSION METHOD |
| 摘要 |
An optical transmitter includes: a digital signal process unit that generates a drive signal for generating multi-carrier signals through a plurality of independent digital signal processes, the multi-carrier signals having a cyclic prefix and to be transmitted by a parallel transmission; a synchronization unit that synchronizes clocks of the plurality of digital signal processes; and an adjust unit that reduces a delay difference of the cyclic prefix between the multi-carrier signals after the parallel transmission. |
