ABSTRACT:
Midamble codes, acting as channel estimation, and information data, as well as system information, will be sent to the joint cell detector. Midamble codes are sent to the estimator of adjacent cell, as well as that of its own cell. As a matter of fact, channel response is sent to channel noise-depressed modules to be depressed. Then the depressed channel is sent to channel window activation detector to receive first activation detection, to see whether the channel windows are activated. Channel response, after detected by channel window, will be sent to multi-user jointed detection unit together with information data. The soft bit information, after having been demoduled or detected, will be transmitted to the following Transport Channel Decoding (TrCH) modules and Channel Decoding (CC) modules. This invention solves the technical problems, that is, interferences received by the user equipments in inter-frequency network from its own cell and the adjacent cells, and to combat the problems of low capacity and handovers.
