We propose a new coded cooperation method for wireless communications to obtain transmit diversity in the scenarios that agents such as mobile handsets, and sensor network nodes, due to size, power or other constraints, cannot utilize multiple antennas. New method supports more than two cooperative users with low cooperation levels. We evaluate the performance of our proposed method in the frequency nonselective slow fading channels. Our numerical results show that each of the N cooperative users obtains the full diversity order of N in moderate-to-high signal to noise ratio regimes. Also simulation results show that the new coded cooperation method can achieve a noticeable gain over non-cooperative networks. Because of the complexity of the general case, we only derive the exact frame error rate for two cooperative users. The analytical results are evaluated by the simulations.
