WIRELESS COMMUNICATION SYSTEM HAVING ANTENNA DIVERSITY.

摘要

A wireless communication system (10) includes a plurality of stations (12) each having a plurality of antennas (14,16). A first packet (120), containing a training signal portion (122) is transmitted from a transmitting station using a first selected antenna and received at a receiving station using a second selected antenna which is selected as the antenna giving the best received signal quality, determined during the training signal period. Following transmission of the first packet, a control signal (ACKCNTL) is generated in both the transmitting station and the receiving station to condition these stations for the transmission from the receiving station of a response packet (136) via the same antenna pair used for the information packet transmission. Thus, the response packet (136) need have only a relatively short training signal portion (138).
