Eavesdropping syndicates in cellular communications

We consider eavesdropping strategies for a syndicate consisting of a number of co-operative eavesdroppers employing selective diversity in a wireless communication cell. The potential for performance improvement over that of a single eavesdropper is analyzed. Performance limits are developed by considering a syndicate with an arbitrarily large supply of eavesdroppers. Optimal configurations are considered under the assumption that eavesdropper cell locations must be fixed prior to activity of the users, although the special case of an arbitrarily large syndicate can be viewed as a single mobile eavesdropper afforded the capability to optimally situate itself upon initialization of the desired user. Cells employing power control are considered along with those that do not.
