| Abstract: |
| In this paper, the bit error rate (BER) performance of cooperative multiple input multiple output (MIMO) system is analyzed and two thresholds for decode and forward (DF) cooperative network are proposed. While the two thresholds are satisfied, the cooperative network may achieve a notable improvement of BER performance compared with the non cooperative network. The analysis and simulation results show that the average BER of cooperation with the two thresholds is much lower than traditional cooperation, and the average BER of cooperation with only threshold one is almost the same as the former scheme and it is much easier to implement |
| Key words: cooperative diversity decode and forward multiple antenna cooperative thresholds |
