Abstract
A TD-SCDMA receiver includes a joint detector that receives an input signal from a transceiver. The joint detector analyzes the input signal to determine whether one or more neighboring cells are used in conjunction with a servicing cell. Also, the joint detector assigns a first matrix that includes all coded channels including those associated with the one or neighboring cells so as to formulate a channel matrix. The joint detector uses a selective ratio that has been minimized to define elements of the first matrix so as to efficiently control the bit-width of the joint detector.
