Aggressive packet combining with consideration of the physical signal and different error control scheme

Aggressive Packet Combining (APC) is one of the most convenient and efficient tool for receiving the corrected version of the transmitted packet. In APC three copies of each packet is transmitted from source to the destination and receiver performs majority logic on the received erroneous copies to extract the correct version. However one of the major drawback of this scheme lies in the fact that it fails to correct the error when erroneous bits are present in two or more transmitted copies or at the same bit location. To overcome these limitations of conventional APC we proposed a new modified version of APC by considering the physical signal through which the transmitted copy can be more efficiently and coherently received by the receiver. Study and analysis made in this paper clearly reveals that the proposed scheme is indeed superior to that of conventional APC
