“…[9][10][11][12][13] The PR filter banks differ largely from the type of system in question in this paper, as they typically involve both decimation and upsampling. In this system, filters generated from the rows of the DFT matrix (see section 3.3) are applied in a circulant manner (see (1)) across both multiple antennas and time slots.…”

Space-time processing for MIMO-OFDM using DFT-based complementary sequences

In this paper, a new space-time signaling scheme is proposed for Orthogonal Frequency Division Multiplexing (OFDM) using complementary sequences derived from the rows of the DFT matrix. The autocorrelative properties of the complementary sequences allows multiple complex data signals at the transmitter with an arbitrary number of antennas to be perfectly separated and reconstructed at the receiver without prior channel knowledge while achieving full-rate. This new method is proposed and derived for multiple MIMO-OFDM systems with multipath fading; at the receiver, symbol estimation is effected via maximum likelihood estimation (ML).
