Abstract
A system includes a transmitter configured to transmit data on a first set of frequencies of a plurality of frequencies. The data transmitted on the first set of frequencies is respectively transmitted using a first set of pre-coding matrices from a plurality of pre-coding matrices. The transmitter is configured to transmit data on a second set of frequencies of the plurality of frequencies. The data transmitted on the second set of frequencies is respectively transmitted using the first set of pre-coding matrices. Transmission of data on the second set of frequencies is subsequent to transmission of data the first set of frequencies.
Claims7
A system comprising:
- a transmitter configured to
- transmit data on a first set of frequencies of a plurality of frequencies,
- wherein the data transmitted on the first set of frequencies is respectively transmitted using a first set of pre-coding matrices from a plurality of pre-coding matrices, and
- wherein data on each frequency of the first set of frequencies is transmitted using a different pre-coding matrix from the first set of pre-coding matrices;
- and
- transmit data on a second set of frequencies of the plurality of frequencies,
- wherein the data transmitted on the second set of frequencies is respectively transmitted using the first set of pre-coding matrices,
- wherein data on each frequency of the second set of frequencies is transmitted using a different pre-coding matrix from the first set of pre-coding matrices,
- wherein transmission of data on the second set of frequencies is subsequent to transmission of data the first set of frequencies,
- 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.
A method comprising:
- transmitting data on a first set of frequencies using a first set of pre-coding matrices, respectively, wherein data on each frequency of the first set of frequencies is transmitted using a different pre-coding matrix from the first set of pre-coding matrices;
- and
- transmitting data on a second set of frequencies using the first set of pre-coding matrices, respectively,
- wherein data on each frequency of the second set of frequencies is transmitted using a different pre-coding matrix from the first set of pre-coding matrices,
- wherein transmission of data on the second set of frequencies is subsequent to transmission of data on the first set of frequencies,
- 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.
