Abstract: Orthogonal Frequency Division Multiplexing (OFDM) based wireless communication system has source encoder and source decoder and channel encoder and channel decoder. Source encoder and source decoder is used to convert the analog signal into digital signal and digital to analog signal, respectively. The main advantages of channel encoding a channel decoding are detecting and correcting a single error as well as detecting more double and triple adjacent errors. To fulfill the OFDM requirement, different types of encoding and decoding techniques such as hamming, Cyclic Redundancy Check (CRC), Low-Density Power Check (LDPC) and some other linear codes are used. In the part of encoding technique, parity bits are added to detect and correct a single error. Similarly, in the decoder side, single bit errors are detected and corrected successfully. In convolutional encoding technique, single bit data is converted into second-bit data sequentially. To detect the data output, convolutional encoder is implemented in this research.
