Interference canceling device and method in mobile communication system |
摘要 |
An interference canceller. A baseband signal is input to a detector's fingers, and the fingers detect multi-path signals and estimate the baseband signal's channel. An MRC uses the finger's despread signal and the channel estimate to output a soft bit decision value, while a signal regenerator uses a hard bit decision value and the finger's channel estimate to regenerate the baseband signal. An SIR measurer uses a soft bit decision value and a despreader's channel estimate to measure an SIR. A signal selector compares each detector's SIR measurement value with a target SIR, and when the SIR measurement value is greater than the target SIR, it selects the detector's regeneration signal to group received signals. A subtractor subtracts the regeneration signal from the baseband signal.
