Abstract
Wireless communication systems are more prone to errors during transmission of messages. But reliable and efficient data transmission is a main topic of interest. Since long time, researchers are working for various error detection and correction (EDAC) technique for error free data transmission. This paper is an attempt to provide basic information about various error detection and correction schemes developed. There are mainly two types of EDAC techniques namely Automatic repeat request (ARQ) and Forward error correction (FEC). Stop & wait ARQ and Continuous ARQ have been discussed in this paper. Further, this paper provides basic information about different types of block codes namely cyclic redundancy check codes (CRC) and Hamming codes. Convolutional code has also been discussed.
