Patent ID: 8619920

Claim:
A receiver configured to recover transmitted symbols from despread data symbols, comprising: a receiving unit configured to receive a prescribed number (SF t ) of data blocks transmitted by a single-carrier transmission scheme, each data block consisting of L sub-blocks; a first despreading unit configured to multiply each of the prescribed number (SF t ) of data blocks by a first spreading code of a first spreading factor SF t to output a despread signal; a phase demodulation unit configured to multiply the despread signal with a user dependent phase to output a phase demodulated signal; a second despreading unit configured to multiply the phase demodulated signal with a second spreading code of a second spreading factor SF f and output data symbols, where L, SF t , and SF f are natural numbers greater than or equal to 2; and a combination of a Fourier transform unit, a frequency domain equalizer, and an inverse Fourier transform unit inserted between the phase demodulation unit and the second despreading unit.
