Patent ID: 8902816

Claim:
A system, comprising: a transmitter configured to transmit data in a first set of time-slots of a plurality of time-slots, wherein the data transmitted in the first set of time-slots is respectively transmitted using a first set of pre-coding matrices from a plurality of pre-coding matrices, wherein data in each time-slot of the first set of time-slots is transmitted using a different pre-coding matrix from the first set of pre-coding matrices; and transmit data in a second set of time-slots of the plurality of time-slots, wherein the data transmitted in the second set of time-slots is respectively transmitted using the first set of pre-coding matrices, wherein data in each time-slot of the second set of time-slots is transmitted using a different pre-coding matrix from the first set of pre-coding matrices, wherein the second set of time-slots is subsequent to the first set of time-slots; and wherein the first set of pre-coding matrices is arranged in a predetermined order, and wherein the predetermined order includes an ascending order, a descending order, or an alternating order.
