Abstract:
1. A method for increasing overall throughput of a multiple access system, said system comprised of at least one transmitter for transmitting data signals using a single channel, and at least one corresponding receiver, the method comprising the steps of: receiving signals through at least two independent signal collectors for each receiver; processing each signal received by each signal receiving collector through a separate preprocessing unit including analog to digital signal conversion, each separate preprocessing unit providing processed digital signals from one of the collectors; connecting an separate parameter estimation unit to the output of each preprocessing unit to receive processed digital signals from one of the collectors; connecting an organizational unit accepting signal inputs from each of the parameter estimation units and processed digital signals from each of the preprocessing units; stacking said signals received from each of said parameter estimation units via the organizational unit into a vector measurement at each time sample; combining separate sets of parameter estimates received from each of said parameter estimation units into a single set in said organizational unit; transmitting said single set of parameters to a multiuser detection unit; outputting a symbol stream for each user from said multiuser detection unit; and using the following to stack the digital received signals into vector measurements at each time sample: time stamp information from each independent signal receiving collector's preprocessed signal.
