Error Control for Integrated Wireless and Wireline Networks

{ To support multimedia applications, future PCS networks will likely involve an advanced interconnected wireless and wireline network. This paper focuses on how a PCS network can compensate for and mitigate the eeects of wireless channel errors. An error control architecture for wireless ATM that utilizes interleaving in the physical layer, forward error correction (FEC) code in the wireless ATM adaptation layer (AAL), and Selective Repeat automatic repeat request (ARQ) in the network layer is proposed. Moreover the FEC scheme in the AAL not only provides header error correction, but also includes error protection for the payload, which is a strong distinction from the traditional ATM implementation to combat channel error.
