Abstract

This paper deals with characteristics and theory of code division multiple access (CDMA), orthogonal frequency division multiplexing (OFDM) and variable spreading factor orthogonal ferquency and code division multiplexing (VSF-OFCDM) systems. As comparison and evaluation of VSF-OFCDM with various 2D spreading factor (SF) as frequency and time dispersive transmission channel according to ETSI standard (typical rural area and warehouse enviroment) is being done.

二维扩频通信系统的特点

本文介绍了码分多址(CDMA)、正交频分复用(OFDM)和变扩展因子正交频分复用(VSF-OFCDM)系统的特点和原理。根据ETSI标准(典型农村和仓库环境)，对不同二维扩频因子(SF)作为频时色散传输信道的VSF-OFCDM进行了比较和评价。
