Videocodingwithh.264
- H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression ef
CDMAchannel
- 语音编码为信源编码，是将模拟信号转变为数字信号，然后在信道中传输。在数字移动通信中，语音编码技术具有相当关键的作用，高质量低速率的话音编码技术与高效率数字调制技术相结合，可以为数字移动网提供高于模拟移动网的系统容量。目前，国际上语音编码技术的研究方向有两个：降低话音编码速率和提高话音质。-Speech coding for source coding is the analog signal into a digital signal, and then in the channel trans
InitialPerformanceEvaluationofDFTSpreadOFDMBasedS
- Abstract—In this paper we present an initial performance evaluation of the 3GPP UTRA Long Term Evolution (UTRA LTE) uplink with baseline settings. The performance results are obtained from a detailed UTRA LTE uplink link level simulator suppo
