Performance Improvement of Downlink MC-CDMA Cellular System using Different Arrival Time of the Adjacent Cell Signal

Abstract (in Japanese) (See Japanese page) 
(in English) Throughput performance of MC-CDMA systems depends on the success in managing interference arising from
intercell transmission. In this paper, we propose a new intercell interference mitigation scheme for downlink MC-CDMA
scheme. In the proposed scheme, a base station transmits downlink signals intermittently to mobile terminals at the edge of
cell. The intercell interference can be seen as a partial interference depend upon the on and off period of the adjacent downlink
signals. So it is possible for the channel equalizer to suppress this partial intercell interference by setting the weight changes
in accordance with the intercell interference. As results, the frame error rate of the proposed scheme is always better than that
of the conventional scheme and good throughput performance is achieved especially when the adjacent cell signal power is
large.
