CDMA Reference Blockset

Main Library Structure

This section describes the structure of the CDMA Reference Blockset and summarizes the functionality of each library. It also explains referencing between libraries and how to open the main library.

Main Library Structure Overview

The main library of the CDMA Reference Blockset, shown below, is organized into these sublibraries:

• IS-95A Base Station Transmitter Library
• IS-95A Mobile Station Receiver Library
• IS-95A Mobile Station Transmitter Library
• IS-95A Base Station Receiver Library
• IS-95A Common Library

  

Functionality of Libraries

Blocks used in the Base Station Transmitter, the Base Station Receiver, the Mobile Station Transmitter, and the Mobile Station Receiver make up four libraries. Blocks that relate to more than one of these functional groups are collected in a fifth library, called Common. Blocks in the Common library include those that generate the different PN codes or determine frame quality.

The transmitter functions are divided between the Base Station Transmitter and Mobile Station Transmitter libraries, depending on their role in either the forward link or reverse link, respectively. The corresponding receiver functions are not described in the standard, but are derived from the corresponding transmitter functions. The receiver functions are divided between the Base Station Receiver and Mobile Station Receiver libraries, depending on their role in either the reverse link or forward link, respectively.

The main library also displays the "Demos" icon. Use this icon to access the demo models, which are described in Demo Models

Reference Between Libraries

The libraries in the CDMA Reference Blockset are true libraries. This means that when you copy a block from a CDMA Reference Blockset library to the model window, Simulink creates a reference to the source block (in the library). Updates made to the source block affect every model block that refers to it. See Using Simulink for complete information about true libraries.

Opening the Main Library

To open the CDMA Reference Blockset, type

• cdmalibv1p1
  

at the MATLAB command line. Double-click on a library icon in the main library window to open that library, and double-click on any icon in a library to open the block's parameter dialog box.
