Effective closed-loop power control method for radio multimedia CDMA communication system

Abstract

The present invention includes the process of dividing the multiuser multimedia jobs of different transmission rate and different QoS requirement into several child job streams; channel multiple connection of the present invention to form closed-loop power control child channels of different QoS requirement; and performing cloed-loop power control to the child job streams. Adopting the closed-loop power control of the present invention multimedia CDMA communication system can meet the requirement of the multimedia jobs in different transmission rates and different QoS while minimizing emittedpower and interference and increasing system capacity.

AI Technical Summary

Benefits of technology

The technical effect of this patented method for improving wireless data communications systems involves dividing up these various types of media (multimedia) services onto smaller groups or channels), which helps them meet their specific needs better while reducing transmitting energy without affecting others' reception capabilities. This approach also increases network efficiency due to more efficient use of available bandwidth resources.

Problems solved by technology

Technologies aim to improve the efficiency and reliability of radiocommunication networks used in multimedia communicating applications like internet browsing, file transferring, media streaming etc., especially when they use various types of devices simultaneously. However, conventional methods require specific resources to handle these challenges without sacrificing their benefits over others. To address this issue, researchers proposed solutions involving dynamic resource allocation techniques, including adaptive modulation and equalization techniques, energy management techniques, and power control algorithms. These improvements help maintain consistence among diverse services despite varying conditions during operation.
