N2 - Conventional transmission schemes perform poorly in wireless channels. In this paper, an analytical adaptive model for wireless links via heuristic TCP/FEC functions is proposed with chosen modulation format for transporting mobile MPEG-4 video. A wireless channel introduces that the bit errors at the link-layer packets are due to the time-invariant features over UMTS network and consequently the optimal perceived video quality at the client can be improved when adaptive TCP throughput after error-corrections is achieved for the certain predefined system threshold of the residual packet error rate. The simulation results show that a video quality can dynamically adapt to the optimal FEC codes at an appropriate selection for modulation scaling in the radio-link layer.
