Abstract:
1. A method for receiving a plurality of data signals over an antenna array having a plurality of antenna elements, the data signals transmitted over a shared spectrum in a wireless communication system, the method comprising: receiving a signal over each antenna element having each of the data signals; grouping the plurality of data signals into a plurality of groups; matched filtering the received signals of the antenna elements for a first group of the plurality of groups, producing a matched filtered result; jointly detecting data of the first group using the matched filtered result; constructing an interference correction signal using the detected data for each antenna element; subtracting from the received signal of each antenna element the interference correction signal for that element, producing an interference cancelled result for each antenna element; and successively detecting data of remaining groups using the interference cancelled result for each antenna element, wherein the jointly detecting data produces soft symbols and the method further comprising converting the soft symbols into hard symbols prior to interference correction signal construction.
