专业的问题，我想还是应该从专业入手。不知道你的问题在哪里，matlab提供的CDMA Reference Blockset和Communications Blockset 可能是和你的问题比较接近的，自己研究一下help吧。



What Is the CDMA Reference Blockset?


The CDMA Reference Blockset is a collection of Simulink® blocks designed to help you develop and simulate CDMA wireless communication systems, based on the current North American IS-95A CDMA (code division multiple access) standard.

With the CDMA Reference Blockset, you can construct block diagram models of wireless systems quickly and easily using click-and-drag mouse operations. You can then run simulations on those models.You can also change parameters. The blocks in the CDMA Reference Blockset encompass the complete functionality required by the IS-95A standard.

Note    The CDMA Reference Blockset is not designed to work with Real-Time Workshop®.

Communications Blockset   
What Is the Communications Blockset?


The Communications Blockset extends Simulink® with a comprehensive library of blocks to design and simulate the physical layer of communication systems and components. The blockset helps you design communications systems and their semiconductor components, such as commercial or defense wireless and wireline systems.

The key features of the blockset are

Blocks for designing and simulating the physical layer of communications systems, including modulation, source and channel encoding, channels, and equalization

The ability to tune models and visualize the results

Hierarchical, block-based models for visually conveying complex designs

Integration with the Communications Toolbox for postsimulation analysis
