| Abstract: | A unitary space-time cooperative diversity based on detect and forward method was studied. It can be well-tailored for flat-fading channels where neither the transmitter nor the receiver knows the fading coefficients. Using the unitary space-time cooperative diversity, the simulation by two-user cooperative system was done. Simulation result shows that the bit error rate is dependent on the characteristics of the user's individual channel and the inter user channel between them. |
