Abstract
A receiving apparatus in a wireless communication system is provided. The receiving apparatus includes a first interference cancellation unit configured to cancel interference from a received signal that is received through an antenna according to a first scheme, a second interference cancellation unit configured to cancel interference from the received signal that is received through the antenna according to a second scheme, and a combination unit configured to combine the signal from which interference is cancelled according to the first scheme and the signal from which interference is cancelled according to the second scheme.
Claims16
A receiving apparatus in a wireless communication system, the receiving apparatus comprising:
- a first interference cancellation unit configured to cancel interference from a received signal that is received through an antenna according to a first scheme and to output a first interference-cancelled signal;
- a first estimation and equalization unit configured to estimate a first channel, to equalize the first interference-cancelled signal based on the estimated first channel and to output a first equalized signal;
- a second interference cancellation unit configured to cancel interference from the received signal that is received through the antenna according to a second scheme and to output a second interference-cancelled signal;
- a second equalization unit configured to estimate a second channel, to equalize the second interference-cancelled signal based on the estimated second channel and to output a second equalized signal;
- and
- a combination unit configured to combine the first equalized signal and the second equalized signal.
A method for operating a receiving apparatus in a wireless communication system, the method comprising:
- canceling interference from a received signal that is received through an antenna according to a first scheme and outputting a first interference-cancelled signal;
- estimating a first channel, equalizing the first interference-cancelled signal based on the estimated first channel and outputting a first equalized signal;
- canceling interference from the received signal that is received through the antenna according to a second scheme and outputting a second interference-cancelled signal;
- estimating a second channel, equalizing the second interference-cancelled signal based on the estimated second channel and outputting a second equalized signal;
- and
- combining the first equalized signal and the second equalized signal.
A receiving apparatus in a wireless communication system, the receiving apparatus comprising:
- a plurality of interference cancellation units connected in parallel to each other and configured to cancel interference from a signal received through an antenna independently according to different methods and to output interference-cancelled signals;
- a plurality of estimation and equalization units, each estimation and equalization unit of the plurality of estimation and equalization units respectively corresponding to an interference cancellation unit of the plurality of interference cancellation units, and each of the estimation and equalization units being configured to estimate a channel and equalize the interference-cancelled signal output from the corresponding interference cancellation unit based on the estimated channel and to output a respective equalized signal;
- a combination unit configured to combine the respective equalized signals and to output a combined interference-cancelled signal;
- and
- a decoder configured to perform decoding on the combined interference-cancelled signal, as combined by the combination unit.
