In this paper a technique is offered for improving the efficiency of communication. The prime objective of any Communication Technique is not only to make the communication clear, efficient and noise free but also to make the communication well secured from its interception from unauthorized users in both commercial as well as in defense communication. For this purpose nowadays the most commonly used technique is frequency hopping. The hopping technique is characterized by its flexibility of changing hopping carrier i.e, change of carrier randomly that is if it is intercepted by unauthorized user the hopping pattern should be changes at any time. There will be no need of synchronization at transmitter and receiver side i.e at any time if the transmission is taking place and the receiver comes into power in the middle of transmission, than the receiver can receive the information at any instant. The error may occurs in the information during passing through the channel, and there will be the need for re-transmission , so for that reason we will apply Hamming code before transmission so that at the receiver side if the error occurred through the channel than that error will be detected and corrected at the receiver side without retransmission because of which the competence will be improved.
