Channels

Description

The Binary Symmetric Channel block introduces binary errors to the signal transmitted through this channel.

The input port is the transmitted binary signal. The input can be either a scalar, a sample-based vector, or a frame-based row vector. This block processes each vector element independently, and introduces an error in a given spot with probability Error probability.

The first output port is the binary signal that has passed through the channel. The second output port is the vector of errors that were introduced. To suppress the second output port, uncheck the Output error vector check box.

Dialog Box

Error probability

The probability that a binary error will occur. The value of this parameter must be between zero and one.

Initial seed

The initial seed value for the random number generator.

Output error vector

If this box is checked, then the block outputs the vector of errors.
