Abstract

In this paper, we study code constructions over the finite ring M2(F2), the ring of 2×2 matrices with coefficients in the finite field F2. We show how they can be related to classical codes over F4. We provide as application the design of outer codes for 2 × 2 space-time coded modulation, when the inner code is the so-called Golden code.
