The issues faced by Complementary metal oxide semi-conductor (CMOS) technology in the nanoregime have led to the research of other possible technologies which can operate with same functionalities however, with higher speed and lower power dissipation. One such technology is Quantum-dot Cellular Automata (QCA). At present, logic circuit designs using QCA have been comprehensively researched and one such application area being investigated is data transmission. Various data transfer techniques for reliable data transfer are available and among them convolution coding is being widely used in mobile, radio and satellite communications. Considering the evolution towards nano communication networks, in this paper an ultra-proficient designs of 1/2 rate and 1/3 rate convolution encoders based on a cost-efficient and fault tolerant XOR gate design have been proposed for application in nano communication networks. Based on the performance analysis, it is observed that the proposed designs are efficient in respect to cell count, area, delay and circuit cost and achieves performance improvement up to 40.21% for 1/2 encoder and 31.81% for 1/3 encoder compared to the best design in the literature. In addition to this, the energy dissipation analysis of the proposed designs is also presented. The proposed designs can thus be efficiently utilized in various nanocommunication applications requiring minimal area and ultra-low power consumption.
