摘要： Embodiments of the present invention provide a method for retransmission based on forward error correction. The method includes: when received source data packets loss occurs, judging whether all of the lost source data payloads can be decoded by using the received source data payloads and check data; if all of the lost source data payloads cannot be decoded, determining needed source data symbols for decoding all of the lost source data payloads by using the received source data payloads and the check data; and requesting for retransmitting the needed source data symbols.

摘要： The present invention provides an acoustic attenuation based on sound ray deflection theory and a muffler. The method of the present invention provides a temperature gradient between the interior and the exterior of the chamber of the muffler through the low temperature refrigeration system, in which the temperature inside the pipe wall is higher than that outside the pipe wall. The said temperature gradient may deflect the acoustic ray towards the low temperature direction, so as to capture and reduce the noise. The muffler of the present invention comprises a muffler housing laid with a sound absorbing structure (4) on its internal surface, is characterized by the low temperature refrigerating system (2) which is fixed in the position corresponding to the sound absorbing structure (4) on the external surface of the muffler housing (1), covers at least 5% of the area of the external surface of muffler housing (1), and is used to realize quantitative control of the temperature gradient together with a temperature control system (3). The muffler of the present invention effectively improves the noise-absorbing effect of the prior muffler.

摘要： A noise elimination method based on sound ray refraction theory and the muffler thereby are disclosed. The method use s low temperature refrigeration system (2) to form a temperature gradient inside and outside the chamber of the muffler, and the temperature inside the pipe wall of the chamber is higher than the outside. The temperature gradient may force sound ray to reflect towards the low temperature direction, so the noise of the system may be captured and reduced. The muffler comprises a housing (1) whose inner wall is laid with a sound absorbing structure (4), and on the outer wall of the housing (1) is provide a low temperature refrigerating system (2). The system covers at least of the area of the outer wail of muffler housing (1) and combines with a temperature control system (3) to realize quantitative control of the temperature gradient. The muffler improves the noise-absorbing effect of the existing muffler effectively.
