Abstract

LAS-CDMA multiple access codes, possessing interference free windows IFW, are combined with multiple transmitting and multiple receiving BLAST system advanced by Bell Laboratory. This compound system greatly increases parallel transportation channels and realize high speed data transmission. In multi-cell networking circumstances, however, there exists severe inter-antenna interference and adjacent cell interference. To overcome the interferences, the receiver combines uniform code joint detection with two-level feedback multi-code detection based on soft demodulation to divide the signals effectively. LAS-CDMA parallel transmitting system provides the reference for the future multi-cell networking systems and becomes an ideal solution for the next mobile communication systems.
