Research of Inter-Cell Interference Suppression Technique for B3G System
Huang Hua-can · Journal of Huaqiao University · 2011
The analysis of being used or have been used for long term evolution(LTE) wireless communication systems Inter-cell interference suppression has been put forwarded.The problem of the interruption coverage in potential signal to interference plus noise ratio was investigated.Including power control technology,space division multiple access antenna techniques,interference cancellation techniques and decoding technology,etc..The research suggest that interference cancellation can bring a significant gain,but because its complexity to dealing with,it′s only applied to LTE uplink,and the base stations also need real-time exchange of information between the millisecond LTE system in order to achieve maximum gain;spherical coding and dirty paper coding decoding technology can provide fairly good gain,but the complexity for dealing limit the UL link applications;power control technology and multiple input multiple output(MIMO) technology is base on the inter-base station technology with the potential performance gain and the feasibility of achievement on base stations.
