<p>First aspect of the invention is a signal processing method comprising steps of demodulating an incoming signal, performing a Fourier transform to the demodulated incoming signal, generating a code word signal, performing a Fourier transform to the code word signal, calculating complex conjugate for the Fourier transformed code word signal, and correlating said complex conjugate of the Fourier transformed code word signal and the Fourier transformed demodulated incoming signal. The first aspect of the invention is mainly characterized in that said code word signal comprises at least two different code words for correlation of multiple different signals from said incoming signal. The invention also concerns signal processing device and system.</p> |
