A Unitary Space-Time Cooperative Diversity Based on Detect and Forward Method

A unitary space-time cooperative diversity algorithm based on detect and forward method is proposed in this paper. It can be well-tailored for flat-fading channels where neither the transmitter nor the receiver knows the fading coefficients. We can know that the bit error rate (BER) is dependent on the characteristics of the user's individual channel and the inter-user channel between them from the computer simulation.
