A Novel ARQ Scheme Applied to Wireless Communication

In wireless communication, ARQ scheme plays an important role for the error control. The two basic ARQ schemes are the Selective Repeat ARQ and the Go-Back-N ARQ. GBN-ARQ scheme is easy to implemented while its throughput is proved to be not so perfect. On the other hand, SR-ARQ performs better than GBN-ARQ while its implementation is too complex. The two basic ARQ schemes cannot satisfy the requirement of the wireless communication. In this paper, an advanced ARQ scheme is proposed to solve the problem mentioned above. The correlative relationship of the key segments of the network data is used to recover the erroneous data. The proposed scheme is analyzed in theories and compared with the basic ARQ schemes by matlab simulation on throughput performance. The simulation results show that the proposed scheme has a lower complexity than that of SR-ARQ and it has a better throughput performance than that of GBN-ARQ.
