Abstract

A selection combining scheme is considered as an upgrade solution to existing wireless networks. The upgrade requires the use of a new radio frequency front end at the receiver with three antennas instead of one. An approach to guarding the system from diversity loss caused by antennas proximity is proposed. As an example, the upgrade of mobile units in an IS-136 network is analyzed. Performance is evaluated by computing the bit error rate, outage probability, average signal to noise ratio and mean switching rate of the considered scheme.
