| Abstract(in English) | In modern cellular system, base station cooperation MIMO in which multiple base stations transmits desired signals to one user is anticipated to alleviate interference at the cell-edge. Cell-edge user is influenced a great deal by interference between different base stations. Inter-cell interference will degrade system performance dramatically. An interference alignment (IA) scheme was proposed recently to eliminate inter-cell interference. It aligns interference into a smaller-dimensional subspace to eliminate interference. Transmit and receive weights in base station cooperation MIMO with IA we shown for the model two BSs and two MSs. In this report, we show transmit and receive weights for the model with three BSs and two MSs and that with two BSs and three MSs. interference alignment scheme. We compare capacity using computer simulation when interference alignment is used with capacity when interference alignment is not used. |
