Abstract
Described are network coding (NC) systems and techniques which utilize multiple composite extension finite fields to reduce complexity at various nodes in a network and also reduce overhead due to signal coding coefficients. A coding design uses a series of finite fields where increasingly larger fields are based on a previous smaller field. Techniques disclosed herein can be applied to existing systems using Random Linear Network Coding (RLNC) or Fulcrum codes.
