Communication Audio and Video Coding and Decoding Methods in Wireless Cooperative Communication Network

Wireless communication is ubiquitous in people’s daily life. As requirements for wireless continue to increase, how improve system performance has become a core issue that researchers pay attention to. cooperative considered be key technology the future because it can provide better quality, higher capacity, wider coverage, richer services, and high spectrum utilization efficiency. The proposed network coding effectively eliminate transmission bottleneck problem faced by communication. development of audio video increased demand services. goal shifting from traditional storage applications transmission. Therefore, being affected academia industry. purpose this paper study codec methods networks understand status reading large number related documents. On basis problem, relevant experiments are designed conduct in-depth research. Experimental results show scheme simplify implementation scalable coding, efficiency enhancement layer, quality reconstructed when streams truncated.
