Forward error correction schemes for wireless ATM systems

Wireless asynchronous transfer mode (ATM) systems have been proposed for future broadband multimedia personal communication. Forward error correction (FEC) is often used to improve the bit error rate (BER) performance of wireless transmission systems. The ATM employs header error control (HEC) to protect the ATM cell header from bit errors. Since ATM specifications have been developed for high-quality optical fiber transmission systems, the HEC has single-bit error correction capabilities. However, wireless ATM requires a more powerful FEC scheme to improve the BER performance resulting in a reduction in the transmission power and antenna size. This concatenation of wireless FEC and HEC of the ATM may affect the cell loss performance. This paper proposes an FEC scheme suitable for wireless ATM and analyzes the performance the proposed FEC scheme.
