Abstract

In this paper, a transmission protocol is firstly introduced based on the OFDM cellular cooperation system. Considering the constraints of the size of mobile terminal, we propose two main cooperative schemes to obtain transmitting diversity which is difficult for common transmission methods to acquire. In our structure, at the same time the destination could cooperatively process the signals from two independent paths, one is direct and the other is via a relay. Both of our two schemes are based on a not-fully-regenerative manner. One of our schemes could be used to achieve uplink transmission diversity, and the other one could be utilized in both uplink and downlink transmission. To enhance the performance of the second scheme in different situation, we recommend three supplementary strategies which could alter adaptively according to the condition. The complexity in our schemes is low, and from the simulation results, we could observe that our cooperative approaches could achieve transmitting diversity and obtain good performance.
