1. A method for spreading of received signals, the method comprising:
generating a first-spread-spectrum-signal (SS1-signal), wherein the SS1-signal is generated by performing a first spreading of a data signal, by a first spreader, wherein the frequency bandwidth (BW) of the SS1-signal is greater than the frequency BW of the data signal;
converting the SS1-signal into an optical SS1-signal, using an optical second spreader;
generating a doubly-spread-spectrum optical signal (optical SS2-signal) from the optical SS1-signal, using the optical second-spreader, wherein the frequency BW of the optical SS2-signal is greater than the frequency BW of the SS1-signal; and
generating a corresponding RF signal (RSS2-signal) from the optical SS2-signal, wherein the frequency BW of the RSS2-signal is greater than the frequency BW of the SS1-signal,
wherein the optical SS2-signal is generated by having the optical SS1-signal manipulated by the optical second spreader, using a spreading-sequence out of at least one spreading-sequence, and
wherein the RSS2-signal is generated for transmitting of the RSS2-signal via a wireless communication network.
