Effect of co-phasing diversity on CDMA downlink capacity
نویسندگان
چکیده
The impact of distributed antennas using co-phasing transmission diversity on downlinkCDMAchannels is examined.An expression is derived that demonstrates that uniform downlink signal-to-interference ratio across users can be achieved by appropriately weighting the distribution of transmit powers across distributed antennas. The capacity of a downlink CDMA system employing distributed antennas with optimum power allocation is then found by simulation.

DS-CDMA Downlink Site Diversity with Frequency-Domain Equalization and Antenna Diversity Reception
The use of frequency-domain equalization based on minimum mean square error criterion (called MMSE-FDE) can significantly improve the bit error rate (BER) performance of DS-CDMA signal transmission compared to the well-known coherent rake combining. However, in a DS-CDMA cellular system, as a mobile user moves away from a base station and approaches the cell edge, the received signal power gets...

Abstract In DS-CDMA high speed wireless signal transmissions, the transmission performance degrades due to frequency selective fading. The use of frequency-domain equalization (FDE) can significantly improve the transmission performance. However, the local average received signal power slowly varies due to distance-dependent path loss and shadowing loss according to the movement of a mobile use...
