Throughput analysis on a scheme of product codes for ARQ protocol

Abstract

In some earlier work, MPC and PRPC are believed to offer higher throughput and better error correction capability at high bit error rate (BER) and large packet size only. An analysis was performed to substantiate this claim of higher throughput and better error correction capability in high as well as in low bit error rate (BER) for large and medium packet size. To conciliation high bit error rate some researchers proposed to use Error Correction Code (ECC) in place of Error Detection Code (EDC) in ARQ scheme. But no irrefutable result is found to justify the idea in terms of throughput. The recent exploration is an attempt to analyze the throughput. In this paper, we investigate the analysis of both PRPC and MPC in a Modified way over Conventional PRPC, and testimony the findings available. We propose a combined protocol of Modified PRPC and MPC, and find that it will offer higher throughput and better error correction capability at high and low BER with medium and large packet size as we have used MPC (Modified Packet Combining) scheme with PRPC (Packet Reverse Packet Combining) scheme in a Modified way by combining BEC (Backward Error Correction) with FEC (Forward Error Correction) Codes especially Product Codes for Communication and Networks by using MATLAB TM software.

Improving Error Correction Capability of Aggressive Packet Combining Scheme by using Half-Byte Packet Reverse Technique and Even - Odd Selection Method

“…In the conventional APC scheme, three copies of a packet is sent and when double bits and single bit error occurs then the correction capability is not affected and it can correct the errors at the receiver side without requesting for retransmission. If P1, P2 is the probability of packet with single bit and double bit respectively, then it is given by [14]:…”
