  • Publication number: 20110075711
    Abstract: A wireless receiver 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. Then, in a case when the signals other than the synchronization signal are the target signals for decoding, the wireless receiver performs despreading with respect to the received signal using the synchronization signal and estimates the signal amplitude of the non-orthogonal code. Subsequently, the wireless receiver eliminates the spread synchronization signal from the received signal using the estimated signal amplitude of the non-orthogonal code and using the synchronization signal. Eventually, the wireless receiver performs despreading and demodulation with respect to the signal having the spread synchronization signal eliminated therefrom and decodes the target signals for decoding.
