摘要： Signal Quality Enhancement is performed directly in a coded domain. Coded Domain-Signal Quality Enhancement (CD-SQE) is applied to an encoded signal populated substantially with encoded signal bits to produce an enhanced encoded signal. The enhanced encoded signal is outputted. Thus, the signal does not have to go through intermediate decoder/re-encoder(s), which can degrade overall speech quality. Computational resources required for a complete re-encoding are not needed. Overall delay of the system is minimized. The CD-SQE system can be used in any network in which signals are communicated in a coded domain, such as a Third Generation (3G) wireless network.
