Abstract
An iterative processing unit iterates equalization processing on a reception signal. A PMI determination unit determines a precoding matrix by taking into consideration an interference amount that is removable by the iterative processing unit. A control information transmission unit transmits information indicating the precoding matrix.
Claims10
A communication device comprising:
- an iterative processing unit that iterates equalization processing on a reception signal;
- a PMI determination unit that determines a precoding matrix by taking into consideration an interference amount that is removable by the iterative processing unit;
- and
- a control information transmission unit that transmits information indicating the precoding matrix.
A communication method comprising:
- a PMI determination step of a PMI determination unit determining a precoding matrix by taking into consideration an interference amount that is removable by an iterative processing unit that iterates equalization processing on a reception signal;
- and
- a control information transmission step of a control information transmission unit transmitting information indicating the precoding matrix.
A communication program causing a computer of a communication device to implement:
- PMI determination means for determining a precoding matrix by taking into consideration an interference amount that is removable by an iterative processing unit that iterates equalization processing on a reception signal;
- and
- control information transmission means for transmitting information indicating the precoding matrix.
A processor determining a precoding matrix by taking into consideration an interference amount that is removable by performing equalization processing on a reception signal.
A communication system including communication devices, the communication system comprising:
- a first communication device including
- an iterative processing unit that iterates equalization processing on a reception signal from a second communication device,
- a PMI determination unit that determines a precoding matrix by taking into consideration an interference amount that is removable by the iterative processing unit, and
- a control information transmission unit that transmits information indicating the precoding matrix;
- and
- the second communication device including
- a precoding unit that performs precoding by using the precoding matrix indicated by the information that has been transmitted by the first communication device.
