Patent ID: 8379690

Claim:
A wireless receiver comprising: a receiving unit that receives a signal obtained by multiplexing a plurality of signals that include a synchronization signal that is spread using a non-orthogonal code not orthogonal to a code for spreading other signals other than the synchronization signal; an amplitude estimating unit that performs, in a case when the other signals are target signals for decoding, despreading with respect to the signal received by the receiving unit using the synchronization signal, and estimates signal amplitude of the non-orthogonal code; a signal eliminating unit that eliminates the synchronization signal in spread form from the signal received by the receiving unit using the signal amplitude of the non-orthogonal code estimated by the amplitude estimating unit and using the synchronization signal; and a decoding unit that performs despreading and demodulation with respect to the signal having the synchronization signal in spread form eliminated therefrom, and decodes the target signals for decoding.
