Convolutional Encoder
Overview
Convolutional encoding is a process of adding redundancy to a signal stream. Lattice's Convolutional Encoder core is a parameterizable core for convolutional encoding of a continuous input data stream. The core allows variable code rates, constraint lengths and generator polynomials. The core also supports puncturing. Puncturing enables a large range of transmission rates and reduces the bandwidth requirement on the channel.
