ALTERNATE TIME-SWITCHED SPACE-TIME BLOCK CODING TECHNIQUE FOR SINGLE CARRIER MODULATION

摘要

The present invention relates to a single-carrier transmission/reception system to which an alternate time-switched space-time block coding technique is applied, and a method thereof. According to the present invention, a single-carrier transmission/reception system, to which an alternate time-switched space-time block coding technique is applied, includes a bit input unit, a symbol mapping unit, a guard-period inputting unit for putting a guard period into a data block, a D/A converting unit, a first wireless signal converting unit, a switch for alternately switching a wireless signal, a transmitter including a plurality of transmission antennas to transmit the wireless signal corresponding to the alternate switching, a reception antenna for receiving a wireless signal of the data block having the guard period, a second wireless signal converting unit, an A/D converting unit, a lapping-around addition unit, a fast Fourier transform (FFT) unit, a channel prediction unit, a maximum rate reception combination unit for receiving the predicted channel and a frequency region signal to perform a maximum rate reception combination according to the predicted channel, an inverse fast Fourier transform (IFFT) unit, and a receiver including a data determination unit.
