TD-SCDMA作为未来3G的三大主流技术标准之一,已经得到业界的广泛认可。在技术创新和市场驱动的双重作用下,TD-SCDMA从概念向产业化的进程正在加快,全球主要设备制造商都在积极跟踪和研发基于TD-SCDMA技术的3G网络产品.文中依据演进次序,从3GPP R99、3GPP R4、3GPP R5、3GPP R6和3GPP R7五个方面对TD-SCDMA系列标准进行了概括的介绍,并对各标准的主要特点和新增功能进行了概述。
As one of the three main technical standards for 3G, Time Division-Synchronization Code Division Multiple Access (TD-SCDMA) has been widely accepted by industry. Technological innovation and the market are accelerating the transformation of TD-SCDMA from conception to industrialization and main manufacturers all over the world are tracking and developing network products based on TD-SCDMA. This paper introduces TD-SCDMA standard set from the aspects of TSM, LCR, HDR, B3G TDD and 4G in the order of evolvement and describes in detail the main features and new functions of each standard.
