现如今,随着电子信息技术的迅猛发展,作为一项关键技术,预编码在国内外掀起了科学研究的热潮。本文结合预编码的概念和我国现阶段的研究现状,对在国际上得以大幅度运用的mimo预编码开展有侧重地分析,以便为电子通讯领域的预编码技术的发展和改进提供科学依据。传统意义上的电子编码方式由于深受无线电通讯的物理作用影响,通过建设基站从根本上予以提高。然而,这种方式仅能使基站数量得到增长,投入成本较高,无法从 Nowadays, with the rapid development of electronic information technology, as a key technology, precoding has aroused the upsurge of scientific research at home and abroad. Combining with the concept of precoding and the status quo in our country at present, this paper focuses on the analysis of mimo precoding which is widely used in the world in order to provide a scientific basis for the development and improvement of precoding techniques in the field of electronic communication. The traditional way of electronic coding is fundamentally improved by the construction of base stations due to the physical effect of radio communication. However, this approach can only make the number of base stations to grow, higher input costs, can not be from
