摘要： A new diversity scheme for orthogonal frequency division multiplexing/multi-input multi-output (OFDM/MIMO) systems. The new diversity scheme, i.e., turbo layered space-frequency coded OFDM (TLSFC-OFDM), uses the turbo principle with space hopping (SH). The TLSFC-OFDM system uses a successive interference cancellation (SIC) algorithm to reduce the number of iterations. As a result, this scheme reduces computational complexity. Simulation results show that the SIC-based TLSFC-OFDM system outperforms a conventional OFDM/Horizontal Bell Labs Layered Space-Time (H-BLAST) system using a horizontal coding scheme.

摘要： A receiving apparatus in an OFDM communication system, in which the receiving apparatus includes a serial-to-parallel converter that converts a serial signal received through an antenna to parallel signals. A pre-processor processes an nth symbol converted in the serial-to-parallel converter using an (n−1)th symbol and an (n+1)th symbol. A Fourier transformer Fourier-transforms the output of the pre-processor and an equalizer equalizes a Fourier-transformed signal. A deinterleaver deinterleaves an equalized signal, a decoder decodes a deinterleaved signal, and a parallel-to-serial converter converts parallel decoded signal to a signal stream.

摘要： A mobile communication system, a transmitter includes a first transmission antenna and a second transmission antenna, and the first and second transmission antennas transmit signals through at least one odd carrier and at least one even carrier. The transmitter determines a first symbol and a second symbol to be used for initial channel estimation of a receiver, encodes the first symbol and the second symbol by a preset transmit diversity scheme for a preset time, and transmits the encoded first and second symbols to the receiver through odd carriers and even carriers of the first transmission antenna and the second transmission antenna. The receiver receives a signal for the preset period, estimates channel frequency responses of odd carriers of the first transmission antenna and channel frequency responses of even carriers of the second transmission antenna, and estimates channel frequency responses of even carriers of the first transmission antenna and channel frequency responses of odd carriers of the second transmission antenna by using the estimated channel frequency responses.
