Abstract(in English) | In next generation mobile communication, high speed and high quality data transmission is required. However, in a DS-CDMA system, when small spreading factor SF is used to achieve high speed data transmissions in a frequency-selective fading channel, an error floor is produced due to large inter-path interference (IPI). The authors have proposed a decision feedback chip-level maximum likelihood detection (DF-CMLD) that can effectively suppress the IPI. In this paper, we combine DF-CMLD with antenna diversity reception and theoretically derive its upper-bounded BER and confirm the BER performance improvement by computer simulation. |
