CDMA Reference Blockset

Using the CDMA Reference Blockset

You can use the CDMA Reference Blockset to develop end-to-end (transmitter-to-receiver) simulation models for forward and reverse communication links. Furthermore, you can reach the simulation stage quickly and focus on the specific components of greatest interest in the design.

The blocks support various modes, rates and types of channels. Some of the important features of the blocks are:

• Multirate functionality: The blocks support operations at all the rates supported by the standard. In operations requiring variable rates (that is, when the data rate may change on the fly), a block operates on an input frame according to the frame's rate input.
• Rate set support: The blocks support both the Rate Set I and Rate Set II specified in the J-STD-008 standard. This gives the blockset the capability to model the operation for some of the IS-95B capabilities.
• Sync, Paging, and Traffic channel support for the forward link: Each forward link block supports operation in the modes corresponding to these three channel types.
• Access and Traffic channel support for the reverse link: Each reverse link block can be used to simulate the Access channel, as well as the reverse Traffic channel.

You can also use components of the CDMA Reference Blockset as an architectural basis to create sophisticated subsystems. The Blockset provides a simulation platform on which you can develop further customized designs or proprietary algorithms for optimizing receiver performance. You can modify existing blocks or develop custom-designed blocks to design models and carry out simulations according to your own needs.

The CDMA Reference Blockset also includes several examples of models of wireless systems, which will help you understand how to use the Blockset. After studying these examples, you will be able to construct your own models, based on the IS-95A standard, using any configurations you require.
