摘要

A wireless system at a base station (1) to calculate uplink signals transmitted from a plurality of remote terminals using a channel common uplink, said system comprising: receiving means (15, 19) including a plurality of elements antenna (19) and receivers (15) to produce measurements of combinations of said uplink signals from said plurality of remote terminals using said common uplink channel; processing means spatiotemporal reception (13) to determine and memorize spatial signatures reception for said plurality of remote terminals using said measurements and to determine and memorize weights demultiplexing spatiotemporal for each antenna element (19) with allow separation signals uplink combinations of uplink signals measured by the antenna elements (19), the weights demultiplexing spatiotemporal for each antenna element (19) an L plurality of weights comprising corresponding to the length of a sliding window; and demultiplexer means spatiotemporal (20) comprising a plurality of time reception filters (22) and an adder (21), each temporary reception filter (22) designed to receive a signal from a corresponding antenna element (19) and a conjugate complex weights demultiplexing spatiotemporal for the respective antenna element (19), the adder (21) designed to add the output of the temporary reception filters (22) in order to still generate separated signals uplink, comprising each corresponding to the length L of the sliding window temporary reception filter (22) a series of delays sampling (27), multipliers (26) designed for multiplying delayed versions in time received signal to an antenna element (19) by respective weights spatio demultiplexing and an adder (28) designed to add the results of the multiplications c on order to generate the output of the temporary reception filter (22).
