Sneha Bawane, V.V.Gohokar

Abstract: Convolutional encoding is a Forward Error Correction (FEC) technique used in continuous one-way and real time communication links. Wireless devices such as hand phones and broadband modems rely heavily on forward error correction techniques for their proper functioning, thus sending and receiving information with minimal or no error, while utilizing the available bandwidth. Major requirements for modern digital wireless communication systems include high throughput, low power consumption and physical size. This paper presents the simulation of convolutional encoder using MATLAB. The performance and analysis has done by changing rates of convolutional encoder and error of binary symmetric channel.

Keywords: Constraint Length, Convolutional Encoder, Data rates, Generator polynomials, Poly2trellis structure.
