Communication method conveys information from a transmitter to receiver over an intermediate medium. The competence of received information is determined by medium and clatter. Therefore, medium and noise directly influence the efficiency of the data received. There is a great need for robust error correction techniques with ever accumulative usage of wireless expedients such as portable electronic items and broadband modems. Modern wireless communication schemes depend on advanced error rectification techniques for their suitable functioning. Hence, transferring and receiving information with less or no error, while utilizing the accessible bandwidth is a foremost proposal. As a result, there is a need for efficient error correction technique for present digital wireless communication systems comprising of high throughput, low power consumption, and less area. Although several block coding techniques have already been in use for error correction, and they are not suitable when dealing received information with random errors. Since convolution coding enables soft information decoding and soft information output which is available at communication channels helps in significantly improving error correction capability, they are preferred over conventional block codes. Convolution codes are best suited as forwarding error correction technique but as the constraint length increases the design decoders becomes very complicated.
