Communications Blockset

Differential Encoder

Encode a binary signal using differential coding technique.

Library

Source Coding

Description

The Differential Encoder block encodes and outputs the binary input signal.

The input m and output d are related by

d(t₀) = m(t₀) +1 mod 2

d(t_k) = d(t_k-1) + m(t_k) +1 mod 2

where t_k is the kth time step.

The input can be either a scalar, a sample-based vector, or a frame-based row vector. This block processes each vector element independently.
