This paper proposes a new adaptive FEC scheme combined with ELN (Explicit Loss Notification) that was proposed for improving TCP performance in wireless cellular networks. In the method, transmission errors on the wireless link are measured at the packet level and the error status is notified the TCP sender with ELN. According to this information, an appropriate FEC code is determined in order to maximize the TCP performance. The paper first compares the TCP performance using Snoop Protocol, ELN and the fixed FEC, through which it finds the appropriate FEC code against given BER (Bit Error Ratio).
