Abstract
One or more embodiments provide an apparatus and a method to estimate channel information even when channel information is not accurately known and design a relay filter based on the estimated information in a two-way relay system where a terminal having a single antenna and a relay exist. A relay apparatus of a two-way relay system includes a receiver, a controller, and a transmitter. The receiver receives a signal from at least one terminal. The controller estimates a channel between the terminals based on the received signal, and calculates a receiver matrix and a precoder. The transmitter transmits a signal precoded by the precoder.
Claims20
A relay apparatus of a two-way relay system, the relay apparatus comprising:
- a receiver configured to receive a signal from a plurality of terminals;
- a controller configured to estimate a channel between the plurality of terminals, and calculate a receiver matrix and a precoder based on the received signal;
- and
- a transmitter configured to transmit a signal precoded by the precoder.
An operating method by a relay of a two-way relay system, the method comprising:
- receiving a signal from a plurality of terminals;
- estimating a channel between the plurality of terminals, and calculating a receiver matrix and a precoder based on the received signal;
- and
- transmitting a signal precoded by the precoder.
A non-transitory computer-readable storage medium encoded with computer-executable instructions that when executed cause a data processing system to:
- receive a signal from a plurality of terminals;
- estimate a channel between the plurality of terminals based on the received signal, and calculate a receiver matrix and a precoder;
- and
- transmit a signal precoded by the precoder.
