Question

how do you demonstrate convultional and clock interleaving matlab?

Answer 1

Convolutional codes are one of the most powerful error correcting codes. It is used in satellite communications, voice band models etc.

According to the application, error correction capabilities can be increased or decreased by the code rate.

In convolutional encoder message bits come in serially instead of blocks as in
case of block codes. Thus an encoder does not require large capacity buffer or
memory elements for encoding. A convolutional encoder generates redundant
bits by performing modulo-2 operation on incoming sequence of bits. The
convolutional encoder can be represented and described by three method
namely state, trellis, and tree diagrams.

Here in this case, convolutional encoder for finite state machine is given. The encoder does not require large capacity buffer or
memory elements for encoding. A convolutional encoder generates redundant

convolutional encoder can be represented and described by three method
namely state, trellis, and tree diagrams. The convolutional encoding and
decoding can be understood by these representations. A finite state machine
(FSM) with given number of shift register stage and input-outputs is given below
