摘要
本论文介绍了信号发生器的发展历程和软件无线电技术的发展，研究了软件
无线电技术在信号发生器中的应用的可行性。
研究了基于 IS-95 标准的 CDMA 蜂窝通信系统前向链路的信道结构以及基于
IS-95 标准的 CDMA 基带信号的产生过程。
在上面的理论基础上利用软件设计了数据源、CRC 编码器、卷积编码器、交
织器、扰码器、Walsh 序列发生器、PN 序列发生器、基带滤波器等模块，在
TMS320C6711 DSK 的硬件平台上实现了基于 IS-95 标准的 CDMA 基带信号发生
器，并在时域和频域对信号进行了测量，结果正确。
This paper introduced the evolution course of the signal generator and the
development of the Software Radio technology, studied the feasibility applying the
Software Radio technology to the signal generator.
This paper mainly studied the channel structures of the forward link in the CDMA
cellular communication system based on the IS-95 standard and the generator process of
the CDMA base-band signal based on the IS-95 standard.
Based on above theoretical basis, this paper designed the data source generator, the
CRC encoder, the convolution encoder, the block interleave, the scrambler, the Walsh
generator, the PN code generator, the base-band filter, etc. Finally, the CDMA
base-band signal generator based on the IS-95 standard was carried out on the
TMS320C6711 DSK hardware platform. It was measured in the time domain and
spectrum domain with satisfactory results.
