A JOINT DETECTION(JD) METHOD FOR ADJACENT CELLS IN TDD-CDMA SYSTEM

摘要

A joint detection(JD) method for adjacent cells in TDD-CDMA system predefines time-slot type and comprises the following steps : network side equipmnet configurating every uplink time-slot type in all the dominated cells, and every cell's BS obtaining every uplink time-slot type in the adjacent cell from net-side equipment; network side equipment congfigurating the time-slot itself, employed training sequence and channelization code sended by every user according to the every uplink time-slot type of every cell and uplink service type of every user; users in every cell sending the uplink data by use of the collocated training sequence and channelization code in the collocated time-slot; BS detecting the activated code channell in the adjacent cells according to received uplink data from the user in adjacent cell and obtaining the employed training sequence by every user according to every time-slot type in adjacent cell, thereby making the BS complete the joint detection in adjacent cells.
