A Combined Technique of SC + MPC + APC to Achieve Higher Error Correction Probability and Throughput Over APC and MPC Techniques in a Wireless Network
In this paper, we present the combined techniques of Selection Combining (SC), Modified Packet Combining (MPC) and Aggressive Packet Combining (APC) for higher probability of packet error correction and packet throughput in three branches diversity system (multi-path) over conventional MPC and APC techniques. The three copies of the same packet are used to transmit from transmitter (Tx) to receiver (Rx) in three paths. Like in conventional SC technique, the Rx checks all the received copies individually from three paths whether the received copies are correct or not using frame checking sequences. If any one of the received copies is obtained, the correct copy then it will discard the remaining copies and request for next packet; otherwise the received erroneous copies will be combined. The combined erroneous copies perform ‘r’ number of pair-wise XORed after the erroneous copies are performed bit converted in MPC technique. If ‘r’ pair-wise XOR operations fail to recover the original copy, then APC technique implements with the converted bit stream. Thus, the simulation results using MATLAB obtain better performance in terms of probability of packet error correction and packet throughput over conventional MPC and APC schemes.
