    摘要： A method, an apparatus and a system for eliminating aliasing noise in a multi-carrier modulation system are disclosed. The method includes: acquiring a first power spectrum density template; acquiring information of in-band subcarriers whose aliasing noise is greater than background noise, and acquiring a difference between the aliasing noise and the background noise of the in-band subcarriers; adjusting the first power spectrum density template according to the information of the in-band subcarriers and the corresponding difference to obtain a second power spectrum density template; and sending signals according to the second power spectrum density template. The method, the apparatus, and the system disclosed herein eliminate the aliasing crosstalk noise, improve the performance and stability of in-band services without involving upgrade or modification of the Customer Premises Equipment (CPE), and are easy to implement.

    摘要： A protection method in a packet transport network is provided. A protection path is established for a service data flow borne on a shared protection ring in the method, where the protection path includes a wrapping protection path and a steering protection path. Firstly, a first service data flow is sent through the wrapping protection path. Then, a service data flow node stops sending a second service data flow subsequent to the first service data flow to the wrapping protection path, and buffers the second service data flow. When the first service data flow completely passes by the service data flow node again, the buffered second service data flow is switched from the wrapping protection path to the steering protection path.
