摘要：
Large area synchronized code division multiple access (LAS-CDMA) technology is an excellent CDMA technology. It has good application in the future wireless communications. If the multi-antenna technique is integrated into LAS-CDMA system, better performance can be obtained. For example, in the uplink of LAS-CDMA system, many antennas are used in each transmitter to transmit data of the same user and the data streams of each antenna are independent. In the view of subscriber, the system capacity is greatly enhanced; in other words, the system has realized the multiplexing function. Meanwhile, many antennas are also used in the receiver to receive the same data stream, so that the receiving diversity is achieved. It helps to increase the system performance by diminishing the bit-error-rate (BER). The LS multiple access codes with spreading factor 64 is used in the simulation and the BER performance of multi-antenna LAS-CDMA system with a single cell is given.
