A multi-cell joint detection method in slotted code division multiple access wireless communication system

摘要

A multi-cell joint-detection method in a time-slotted CDMA system includes: performing a multiple code set channel estimation on received signal data and obtaining channel estimation results of a home cell and of neighboring cells; adjusting the channel estimation results of the home cell and/or neighboring cells or the estimation result of a combined channel response according to a comparative delay difference between signals of users in different cells; and performing a joint-detection according to the estimation result of the combined channel response obtained by adjusting the channel estimation results of the users in different cells or according to the estimation result of the combined channel response. The MAI between neighboring universal-frequency cells having comparative delays and especially large comparative delays is greatly suppressed and the performance of the time-slotted CDMA system when working in neighboring universal-frequency cells is improved.
