    receiving the packet with the receiving device, in accordance with one or more of said plurality of antennas;

    evaluating at least one of the plurality of test words in the received packet based on a comparison with a predefined criteria;

    analyzing data reception properties associated with receiving the packet based on the evaluating step;

    selecting one of said plurality of antennas for respective reception of each of said fragments, based on the analyzed data reception properties;

    receiving with the selected antenna until another antenna is selected exhibiting highest reception quality; and

    at least one of;
