Wireless Communication technology is deeply rooted in history. This field has grown to a wide area in a very short interval of time. Over the past 100 years, wireless communication has been prominently developed from satellite transmission, radio and television broadcasting to common mobile phones. Wireless communication is a rapidly developing area in the communications scenario. In the present world, wireless communication has established itself as a crucial component. Practice of digital systems expands the performance and efficiency of wireless communication systems. During the 1990s, the concept of wireless communication suddenly acquired more flesh and blood due to the growth in technology. The omnipresence of computers and, particularly, the invention of the World Wide Web and the massive development of Internet use, have concretized the originally abstract idea. The mobile internet and multimedia are current favourite topics of the press, industry thinkers, management professionals and successful populists. The world is moving towards 5 G, LTE, high speed video and audio streaming. For all these data services, we need rapid and reliable data transmission. The essential prerequisite for reliable data transmission techniques, are the major issues associated with error control. Quality maintenance is one of the major issues in the current communication system. The immoderately presented ideas of wireless communication specify evidently, that this topic should be explored more. Researchers from many fields, namely mathematics, Physics, electrical engineering, Information theory shook their hands to resolve these issues. Error control schemes play an important role in sending reliable and efficient data in digital communication systems. The quality of transmitted data can be improved by using various coding schemes. Coding schemes help in detection and correction of errors in the received signal. Because of these reasons, many error control techniques have been developed.
