Patent ID: 8542659

Claim:
A system comprising: a training field generator module configured to generate a plurality of training fields to be transmitted in a packet to a plurality of client stations; a stream generator module configured to generate a plurality of streams to be transmitted in the packet, wherein first streams of the plurality of streams (i) are designated for a first client station of the plurality of client stations and (ii) include the plurality of training fields, and wherein second streams of the plurality of streams (i) are designated for a second client station of the plurality of client stations and (ii) include the plurality of training fields; and a cyclic shift delay module configured to apply a plurality of cyclic shift delay values to the plurality of streams, wherein first values from the plurality of cyclic shift delay values are respectively applied to the first streams, wherein second values from the plurality of cyclic shift delay values are respectively applied to the second streams, and wherein at least one of the second values is equal to one of the first values; and wherein a total number of training fields transmitted to each of the plurality of client stations is equal to a total number of streams in the plurality of streams.
