Abstract
Methods and devices for communicating in a communication system are described herein. One aspect provides a method of communicating over one or more space-time streams. The method includes transmitting a first stream with a bandwidth of 2 MHz or less. The method further includes transmitting, when there are at least two streams, a second stream with a cyclic shift delay relative to the first stream equal to half a period. The method further includes transmitting, when there are at least three streams, a third stream with a cyclic shift delay relative to one of the first and second stream equal to a quarter of the period. The method further includes transmitting, when there are at least four streams, a fourth stream with a cyclic shift delay relative to the other of the first and second stream equal to a quarter of the period.
