Title:
METHOD FOR RECEIVING AND TRANSMITTING SIGNAL, TRANSMITTER, RECEIVER, AND OPTICAL NETWORK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/004829
Kind Code:
A1
Abstract:
Disclosed are a method for receiving and transmitting a signal, a transmitter, a receiver, and an optical network system. The method for transmitting a signal in an embodiment of the present invention comprises: receiving first signals and second signals, and performing pulse amplitude modulation on the first signals and the second signals to output third signals, wherein the first signals and the second signals are M level signal, the third signals are 2M level signals, and M is a positive integer; and performing optical carrier modulation on the third signals to output optical signals, wherein a bias voltage of a modulator is V=2Vpi*N, Vpi is a difference between a voltage corresponding to a maximum output power and a voltage corresponding to a minimum output power of the modulator, and N is a positive integer. Embodiments of the present invention reduce a carrier-to-signal power ratio (CSPR) and improve system performance.
