A Software Defined Radio Access Network based on inter-cell interference suppression

The convergence of optical and wireless network has led to the trend of future access network . Under the study of Software Defined Radio Access Network(SD-RA) and Soft Frequency Reuse(SFR) system model, this paper presents a new inter-cell interference suppression algorithm of SD-RA network. The paper also summarizes and analyses the difference between the SFR based on coordinate multi-point transmission (CoMP) and SD-RA. The computer simulation results show that the inter-cell interference suppression algorithm can bring about 5dB SINR (Signal to Interference plus Noise Ratio) gain.
