The problem of error control strategies in wireless multimedia networks adopting the ATM protocol is addressed. In particular, we investigate the performance attainable by using a hybrid combination of automatic repeat request (ARQ) techniques and forward error correcting (FEC) codes for class C, connection oriented, non-delay critical and variable bit-rate services. To mitigate the wireless channel impairments we propose an adaptive error control scheme that chooses the control technique for each connection according to its requirements described by the connection specific parameters (e.g. maximum delay and cell loss ratio). The analysis is carried out for an OFDM/QPSK modulation format over a typical indoor radio channel.
