| Abstract(in English) | ZCZ-CDMA with a block spreading technique (BC-ZCZ-CDMA), that a data block is decoded by using a spreading sequence with a zero correlation zone (ZCZ sequence), can remove the multiple access interference for large delay spread with high-speed transmission. The inter symbol interference can be almost removed by the Rake receiver with a pilot-symbol-aided channel estimation. For large-capacity transmission, it is necessary to increase the block size K. However it is takes time of the cube order of the block size L, O(K^3), for calculation of the inverse matrix in the rake receiver. This paper considers BC-ZCZ-CDMA that a transmission uses L ZCZ sequences. It is O((K/L)^3) for the calculation. In addition, the communication performance of BC-ZCZ-CDMA is investigated. |
