Title The study of the technology of coordinated multi-point in mobile communication
Abstract
With the growing business demand for cellular mobile communication, the improvement of capacity of cellular mobile communication system is imminent. However, the inter-cell interference is one of the key factors that affect the performance of the communication system. So this paper studied the application of beamforming algorithms in inhibition of the inter-cell.
First, this paper gave the principle and model of inter-cell interference. Then we studied the beamforming technology in the Coordinated Multi-Point transmission technology and mainly discussed several classical beamforming algorithms. Then we proposed a scheme combing the limited feedback information with beamforming algorithms. And the article compared the performance of different beamforming algorithms, such as the average rate, the cumulative probability distribution of the rate and so on. Based on this, we obtained SLNR beamforming algorithm is better than other beamforming algorithms for improving communication performance. Finally, we also discussed the performance of the communication under different limited feedback. We just focus on the quantization codebook designed by the part of the channel state information. The simulation results show that the communication system in the Grassmannian 6 bit has been very close to the exact channel.
