Abstract

In this paper we present a novel framework to convert the K-user multiple access channel (MAC) over \FF_p^m into the K-user MAC over ground field \FF_p with m multiple inputs/outputs (MIMO). This framework makes it possible to develop coding schemes for MIMO channel as done in symbol extension for time-varying channel. Using aligned network diagonalization based on this framework, we show that the sum-rate of (2m-1)logp is achievable for a 2× 2× 2 interference channel over \FF_p^m. We also provide some relation between field extension and symbol extension.
