Abstract
Provided are a DFT-spread OFDM transmitter and transmission method and a DFT-spread OFDM receiver and reception method capable of receiving the transmitted signal with a frequency domain spectrum shaping vector designed to easily trade off PAPR for spectral efficiency without inter-symbol interference, the DFT-spread OFDM transmitter including a phase shifter for generating a pi/2 PAM symbol vector by phase-shifting a symbol vector including M PAM symbols, a DFT spreader for generating a DFT-spread pi/2 PAM symbol vector by spreading the pi/2 PAM symbol vector using an M-point DFT matrix, a frequency domain spectrum shaper for generating a frequency domain spectrum shaped pi/2 PAM symbol vector by multiplying each element of the DFT-spread pi/2 PAM symbol vector by each element of a first shaping vector including one or more zero (0) elements, and a sub-carrier allocator for allocating a non-zero element in the frequency domain spectrum shaped pi/2 PAM symbol vector to a sub-carrier in an allocated frequency range.
