We study coding techniques for the single-relay nonorthogonal amplify-and-forward half-duplex relay fading channel. Unlike the multiple-antenna case, we show that 2 × 2 rotations induce large gains in outage probability with no increase in decoding complexity under iterative probabilistic decoding. We compare rotated and unrotated turbo-coded schemes and show that they both perform close to their corresponding outage limits.
