摘要： A system and method for XOR Based FEC are proposed. In order to achieve better capacity of recovering packet loss and keep the simplicity of XOR operation, the proposed FEC presents a strategy to generate as many redundant FEC packets as needed by grouping all packets in a matrix according to various predetermined rules. An FEC packet is generated for each group. The FEC applies XOR operation instead of RS codes to protect IP or higher level packets which facilitates software implementation.
