HSOPA实现的关键技术

Key Technology for Realization of HSOPA

文中根据3GPPR5,R6版本协议的技术声明以及现在通信技术的需求,介绍了即将被商用的HSDPA(高速下行分组接入技术)的演进技术——HSOPA(高速OFDM分组接入技术)。文中从3G技术的发展谈起,引出所要讨论的HSOPA技术,随后简单介绍了HSOPA的技术特点,并着重介绍了HSOPA的关键技术(OFDM及MIMO技术等),最后展望了HSOPA技术向后3G及4G的过渡情况,提出所讨论的HSOPA技术的可实现性。

In accordance with the specifications of 3GPP Release 5 and Release 6 and the request of communication technology, this article presents the evolution of HSDPA——HSOPA. It briefly describes the advantages of HSOPA, puts emphasis on the key technology of HSOPA, including its realization. And then it looks forward to the transition from HSOPA to the Beyond 3G and the 4G.
