In preceding few years, further efforts has been done on error detection and error correction in digital transmission systems. This paper proposed the modified parity generator and parity checker circuits using QCA whose polarizations are improved and the output signal is found vigorous. QCA projected a new method to estimation in that arrangement of information at a circuit accomplished using electrons place in the quantum cell. As a result, the digital devices are more acceptable in noisy environment and they can perform more consistent.
