 note = {One of the most challenging and important issues in wireless asynchronous transfer mode (ATM) is the data link control (DLC) protocol. For each different service type, the DLC protocol should provide an appropriate error control mechanism to protect against the relatively poor characteristics of the wireless medium.
　In this thesis, the quality of services (QoS) is classified into two kinds, which have different formats of wireless ATM cells in DLC protocols. For the stream mode services, such as audio and video, forward error correction (FEC) schemes in DLC protocols should be applied to correct and filter out erroneously received ATM cells before they enter the low error rate fixed network. In general, header bits are considered to be more important than payload bits so as to require two-level unequal error protection (UEP). Then, the code (FEC-H) for the header is assigned with a low local coding rate RH to ensure correct deliveries and a low cell loss rate. At the same time, the code (FEC-P) for the payload is designed to be with a higher rate Rp than the one of FEC-H for effective transmissions. For the packet mode services such as data transfer, some buffering delay can be tolerated, then hybrid automatic repeat request (HARQ) schemes are applied. Since the channel state temporarily varies, it is preferable to correct the frequent error-patterns and less-frequent error-patterns by FEC and ARQ technologies, respectively. 
　Most of schemes in the DLC protocols of wireless ATM only adopt block codes (BCs), however, ..., 2000, Includes bibliographical references},
