Abstract
Based on V.A. Zinoviev´s (1981) generalized concatenated codes, conditions for the construction of 90° phase-invariant QAM are derived. Furthermore, a proposal for the necessary differential encoding/decoding is made. The conditions for phase invariance are specialized for the case of Reed-Muller codes as outer codes of the generalized concatenation
