Barcodes are used for wireless data transmission between electronic devices.They are machine readable digital data.Communication is the basic attraction of mankind as it gives knowledge of what is happening around us.Transmission of information is the communication Channel.The need is to deal with methods that allow to improve the transmission quality.Problem is quality of the transmission is ever increasing demand.The aim of the project is using the methods like QPSK-withTCM-OFDM for better data transmission.when compared with other methods.The bit-error-rate is less for TCM than other methods.
