Abstract
A communication device includes an RF receiver that receives a combined signal including a first signal transmitted from a first node and a second signal transmitted from a second node, a channel estimator that estimates first channel information of the first signal and second channel information of the second signal, respectively, a multiuser detector that detects original signal values of the combined signal using the estimated first and second channel information and an RF transmitter that transmits a signal generated based on the values detected by the multiuser detector to the first node and the second node during a predetermined period.
Claims6
A communication method comprising:
- receiving a combined signal including a first signal transmitted from a first node and a second signal transmitted from a second node;
- estimating first channel information of the first signal using a first pilot signal and second channel information of the second signal using a second pilot signal;
- detecting original signal values of the combined signal using the estimated first and second channel information;
- decoding a vector composed of the original signal values detected by a multiuser detector using a first channel code;
- encoding the decoded vector using a second channel code to generate an encoded vector;
- and
- transmitting a third signal generated based on the encoded vector during a predetermined period to the first node and the second node, wherein the third signal represents the encoded vector.
