朗讯科技贝尔实验室的研究人员日前宣布推出全球第一款Turbo解码器芯片,并公布其体系结构和性能详细信息。这款芯片用于第三代(3G)无线数据终端,支持不断发展的高速下行分组接入(SHDPA)标准。这款芯片将授权无线数据终端厂家生产,它足以处理高达24Mbit/s的数据速率——几乎比目前最先进的移动网络快十倍。 HSDPA大大加强了通用移动电信系统(UMTS),也称为扩展带码分多址(W-CDMA)技术。该芯片的速度之快不仅可以支持传输速度在5～10Mbit/s的第一代HSDPA
Researchers at Lucent Technologies Bell Labs announced the launch of the world’s first Turbo decoder chip and announced details of its architecture and performance. This chip is for third generation (3G) wireless data terminals and supports the evolving High Speed Downlink Packet Access (SHDPA) standard. The chip will authorize manufacturers of wireless data terminals, it is sufficient to handle data rates up to 24Mbit / s - almost ten times faster than the most advanced mobile networks. HSDPA greatly enhances Universal Mobile Telecommunications System (UMTS), also known as Extended Code Division Multiple Access (W-CDMA) technology. The chip’s fast speed can not only support the first generation of HSDPA transmission speed of 5 ~ 10Mbit / s
