PROBLEM TO BE SOLVED: To provide a signal receiver that can prevent a data transmission rate from being deteriorated. SOLUTION: The signal receiver 200 extracts only a direct wave from a received signal resulting from multiplexing a data signal and a PN signal and is provided with a PN generator 210 that generates the PN signal, a multiplier 206 that converts the received signal into a base band signal, an impulse response estimate unit 212 that introduces an impulse response estimate value on the basis of the base band signal and the PN signal, a received signal replica generating section 222 that generates a replica of the received signal on the basis of the data signal, the impulse response estimate value and the PN signal, a subtractor 224 that subtracts the replica of the received signal from the base band signal, a square value calculation unit 226 that calculates a square of a subtracted value and a maximum likelihood estimate type equalizer 228 that introduces the data signal on the basis of the square value. |
