Abstract:
1. An apparatus for processing asynchronous data in a multiple access system, comprising: A plurality of received signals from a corresponding plurality of users, wherein said received signals are divided into blocks of data for each of said users; A plurality of multiuser detector processors coupled to said received signals, wherein each of said multiuser detector processors processes a portion of said blocks for each of said users within a processing window; A plurality of decoders coupled to said multiuser detector processors, wherein said decoders process all the blocks for one of the users, once said multiuser detector processor is finished processing an entirety of one of said blocks for the one of said users; and A parameter estimator coupled to said received signals and to said multiuser detector processors, wherein a size of said processing window is determined by said parameter estimator.
