Abstract
A receiver is provided, which includes an antenna configured to receive a plurality of superposition coded signals from a plurality of base stations; and a signal processor configured to perform decoding of a plurality of layer signals included in the superposition coded signals by decoding an uppermost layer signal among the layer signals through applying Gaussian approximation only to remaining layer signals except an upper layer signal which is a next uppermost layer signal among the layer signals.
Claims14
A receiver comprising:
- an antenna configured to receive a first superposition coded signal from a first base station and a second superposition coded signal from a second base station, wherein each of the first and second superposition coded signals is generated based on different layer signals;
- and
- a signal processor configured to decoded an uppermost layer signal from a plurality of layer signals of the first and second superposition coded signals by applying Gaussian approximation to remaining layer signals,
- wherein the remaining layer signals are layer signals except the uppermost layer signal and an upper layer signal among the plurality of layer signals, the upper layer signal being a next uppermost layer signal among the plurality of layer signals.
A decoding method of a receiver, the method comprising:
- receiving a first superposition coded signal from a first base station and a second superposition coded signal from a second base station;
- and
- decoding an uppermost layer signal from a plurality of layer signals of the first and second superposition coded signals by applying Gaussian approximation to remaining layer signals,
- wherein the remaining layer signals are layer signals except the uppermost layer signal and an upper layer signal among the plurality of layer signals, the upper layer signal being a next uppermost layer signal among the plurality of layer signals.
