摘要： A signal reception device is disclosed that is able to improve interference cancellation capabilities even when signals having different center frequencies exist on the same frequency band. The signal reception device includes an interference suppression unit to generate replicas of plural signals in the received signal and separate the signals by suppressing interference signals. The interference suppression unit includes a signal phase rotator to rotate phases of the signal candidates at preset respective rotational frequencies, the preset rotational frequencies being related to respective center frequencies of the signals in the received signal; a rotational frequency controller to set the preset rotational frequencies; and a replica generator to generate the replicas of the signals by using the phase-rotated signal candidates.

摘要： A signal separator for separating multiple signals contained in a received signal from each other based on a replica of the received signal is provided. The signal separator comprises a sampling unit configured to sample the received signal at a prescribed sampling timing; an index output unit configured to monitor sampling counts of the sampling unit and output an index signal representing a remainder of a division dividing the sampling counts by a sampling number per a prescribed time period to group the sampled signals; a coefficient-variable filter configured to generate and output a replica of the received signal based on a channel estimation value and a signal point candidate, at least one of the channel estimation value and the signal point candidate being generated according to the index signal; a subtractor configured to subtract the replica from the sampled signal and output a subtraction result as a residual signal; and a maximum likelihood sequence estimator configured to estimate a sequence for each of the multiple signals based on the residual signal, taking into account signal state transition, and output the estimation result at a signal output timing determined by the index signal.
