Cooperative transmit diversity based on superposition modulation
Erik G. Larsson, B.R. Vojcic · IEEE Communications Letters · 2005
We propose a new strategy for cooperative transmit diversity based on superposition modulation and multiuser detection. The new scheme can outperform "classical" cooperative diversity based on decode-and-forward by about 1.5-2 dB in the SNR range of interest and at the same computational complexity.
