摘要 本文针对蓝牙的同步话音信道仅能支持最多3路的不足,提出了以UWB作为物理传输话音的模型,在分析UWB应用于Bluetooth的前提基础后,给出了其系统实现的协议栈结构,并着重分析了UWB的话音容量并进行仿真分析,使得改进后的蓝牙设备能够高速多路传输实时话音。 Based on the deficiencies of SCO only supporting a maximum of three voice channel, UWB proposed as a physical model for the transmission of voice, applied to the analysis of UWB/Bluetooth based on the premise, given its system to achieve the protocol stack structure, and focus on the analysis of UWB voice capacity and simulation analysis, After making improvements to the Bluetooth equipment to high-speed multi-channel real-time voice transmission.
