A decoder receives packets containing uncoded and coded symbols. When a packet with a coded symbol is received, the decoder determines whether a packet sequence number is within a sliding window of w consecutive sequence numbers that are no greater than a decoder sequence number, where the number w is fixed prior to encoding. When this is the case, the decoder decodes the coded symbol into one or more of the w input symbols using the coefficient vector. Decoding may use a forward error correcting (FEC) window within the finite sliding window. Decoding also may use a technique of Gaussian elimination to produce a "shifted" row echelon coefficient matrix.}, keywords = {}, pubstate = {published}, tppubtype = {patent} }

A sliding window version of RLNC is proposed where the coded packets are generated using packets in a window size and are inserted among systematic packets in different paths. The packets are scheduled in the paths in a round robin fashion proportional to the data rates. We use finite encoding and decoding window size and do not rely on feedback for closing the sliding window, unlike the previous work. Our implementation of two paths with LTE and WiFi characteristics shows that the proposed sliding window scheme achieves better latency compared to the block RLNC code. It is also shown that the proposed scheme achieves low latency communication through multiple paths compared to the individual paths for bursty traffic by translating the throughput on both the paths into latency gain.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }
