Description

technical field

[0001] The invention relates to the technical field of wireless communication, in particular to a code division multiple access (CDMA) uplink dedicated physical channel multi-user receiving device. Background technique

[0002] The CDMA system has become the development direction of the third generation mobile communication because of its advantages of high capacity, high service quality and good security. CDMA systems rely on signature codes to distinguish users, which will cause two problems in the mobile communication environment, namely multipath interference and multiple access interference (MAI). The invention of RAKE receiving technology enables single-user receivers to use multipath components to generate multipath diversity gain, while MAI limits the improvement of CDMA system capacity, coverage and performance. The single-user receiver cannot eliminate the influence of MAI on user signal detection, and the detection performance of the receiver will...
