Communications Blockset

Structure of the Demo

This example contains these blocks from the Communications Toolbox.

Communications Blockset Block	Purpose in Example
Bernoulli Binary Generator	Create random bits to use as message.
Convolutional Encoder	Encode message using the convolutional coding technique.
Puncture	Remove bits from the output of the Convolutional Encoder.
BPSK Modulator Baseband	Modulate encoded message to prepare for transmission.
AWGN Channel	Transmit data, adding random numbers to simulate a noisy channel.
Insert Zero	Insert zeros to substitute for bits removed by the Puncture block.
Viterbi Decoder	Decode the convolutional code using the Viterbi algorithm.
Error Rate Calculation	Compute the proportion of discrepancies between original and recovered messages.
