Abstract  Abstract

PROBLEM TO BE SOLVED: To achieve transmission diversity on a legacy single-antenna receiving device.

SOLUTION: In order to obtain transmission diversity a transmission entity uses different pseudo-random steering vectors across subbands and uses the same steering vector across packets for each subband. A receiving entity does not need to know the pseudo-random steering vectors and further does not need to perform any space processing. For space spreading the transmission entity uses different pseudo-random steering vectors across the subbands and uses different steering vectors across the packets for each subband. Only the transmission and the receiving entities know the steering vectors used for data transmission.
