Abstract
A method includes determining a number of polarizations. The method also includes determining a number of receive antennas that have a same polarization, determining a total number of receive antennas based on the number of polarizations and the number of receive antennas that have the same polarization; and applying singular value decomposition precoding on all the receive antennas with the same polarization.
Claims20
A method, comprising:
- determining a number of polarizations;
- determining a number of receive antennas that have a same polarization;
- determining a total number of receive antennas based on the number of polarizations and the number of receive antennas that have the same polarization;
- and
- applying singular value decomposition precoding on all the receive antennas with the same polarization.
An apparatus, comprising:
- at least one processor;
- and
- at least one non-transitory memory including computer program code,
- the at least one non-transitory memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
- determine a number of polarizations;
- determine a number of receive antennas that have a same polarization;
- determine a total number of receive antennas based on the number of polarizations and the number of receive antennas that have the same polarization;
- and
- apply singular value decomposition precoding on all the receive antennas with the same polarization.
A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, the operations comprising:
- determining a number of polarizations;
- determining a number of receive antennas that have a same polarization;
- determining a total number of receive antennas based on the number of polarizations and the number of receive antennas that have the same polarization;
- and
- applying singular value decomposition precoding on all the receive antennas with the same polarization.
