A system including a training field generator module, a stream generator module, and a cyclic shift delay module. The training field generator module generates training fields to be transmitted in a packet to client stations. The stream generator module generates streams to be transmitted in the packet. First streams (i) are designated for a first client station and (ii) include the training fields. Second streams (i) are designated for a second client station and (ii) include the training fields. The cyclic shift delay module applies cyclic shift delay values to the streams. First cyclic shift delay values are respectively applied to the first streams. Second cyclic shift delay values are respectively applied to the second streams. At least one of the second cyclic shift delay values is equal to one of the first cyclic shift delay values. Alternatively, the second values are different than the first values.
