Layered Subspace Codes for Network Coding
Subspace codes were introduced by Kotter and Kschischang for error control in random linear network coding. In this paper, a layered type of subspace codes is considered, which can be viewed as a superposition of multiple component subspace codes. Exploiting the layered structure, the authors develop two decoding algorithms for these codes. The first algorithm operates by separately decoding each component code. The second algorithm is similar to the Successive Interference Cancellation (SIC) algorithm for conventional superposition coding, and further permits an iterative version.
