CDMA system combined with multiple antennas is very promising in the B3G and 4G wireless communication because its high spectral efficiency. Multiple antennas in CDMA system always perform on two sides: providing diversity gain or spatial multiplexing, which lead to the tradeoff between system BER performance and its capacity. In this paper, a new multiple antenna transmission scheme which not only...
In future wireless communications, there will be a mixture of different traffic classes, which have their own load and quality-of-service (QoS) requirements. In this paper, a traffic load and QoS-oriented packet scheduling (TLQS) is proposed for WCDMA communications, which consider the bit error rate (BER), packet loss, delay and traffic load requirements. The BER requirement can be guaranteed by...
