Communications Blockset

Using Block Encoders and Decoders Within a Model

Once you have configured the coding blocks, a few tips will help you place them correctly within your model:

• If a block has multiple outputs, the first one is always the stream of coding data.

• The Reed-Solomon and BCH blocks have an error counter as a second output.

• Be sure the signal sizes are appropriate for the mask parameters. For example, if you use the Binary Cyclic Encoder block and set Message length K to 4, the input signal must be a vector of length 4.

• If you are unsure about the size of signals in your model, selecting Signal dimensions from the model's Format menu might help.
