A communication system is provided. A first communications device transmits at least one first message including predetermined bit sequences. A second communications device determines one or more antenna weighting vectors (AWVs) and one or more bitloading vectors (BLVs) by using the first message in accordance with a predetermined rule and transmits a second message including information pertinent to the AWVs and the BLVs to the first communications device. The first communications device further communicates with the second communications device about an AWV selected from the AWVs and the first and second communications devices apply the selected AWV to the corresponding antennas before exchanging data. The data includes a header carrying information pertinent to a BLV selected from the BLVs used to encode the data and a payload is transmitted to the second communications device. The second communications device decodes the data in accordance with the selected BLV.

A method of multi-site testing a batch of semiconductor units using a multi-site automated tester (100). The tester (300) includes a handler (320) coupled to a contactor (330) including a first plurality of contact sites. The method includes the step of loading the first plurality of units into the first plurality of contact sites (201). The first plurality of units are simultaneously tested (202) using a test program to determine bin information for each of the first plurality of units, wherein the bin information defines each of the first plurality units as being a passed unit or a reject unit. The passed units are offloaded from respective contact sites of the first plurality of contact sites to create vacant contact sites (203), while keeping the reject unit(s) at respective contact sites of the first plurality of contact sites. Untested units from the batch are then loaded to fill the vacant contact sites (204). Simultaneously, the reject units retested and untested units are tested using the test program (205).
