Abstract :
A simple and effective metric for antenna diversity in DECT is introduced. Using a segment of only 2 to 4 bit periods, this metric provides a reliable estimation of the received signal quality. To emulate ideal selection diversity in a single receiver, this metric is calculated by performing two successive measurements on each antenna during the DECT preamble. When using a correlative clock timing, this diversity provides a performance improvement similar to an ideal CRC-driven selection diversity employing two parallel receivers. This offers a cheap and simple solution to DECT outdoor applications such as PCS
