Claim One:
1. A MIMO OFDM system employing N T transmit antennas and N R receive antennas for data transmission, the MIMO OFDM system comprising: a transmitter, comprising: a channel encoder for receiving information bits and outputting coded bits; a constellation mapper for converting the coded bits into constellation symbols according to constellation mappings; a tone-level interleaver for receiving the constellation symbols and using a symbol block of N T constellation symbols as its basic unit for interleaving; a parser for parsing interleaved symbol blocks and outputting parsed signals to each corresponding transmit antenna; and multicarrier modulators for modulating the parsed signals before the parsed signals are transmitted through the corresponding transmit antennas; and a receiver, comprising: multicarrier demodulators for demodulating received signals passed through a MIMO channel formed by the transmit and receive antennas; a tone-level deinterleaver for deinterleaving the received signals after demodulation, and outputting deinterleaved symbol blocks; and a channel decoder for decoding the deinterleaved symbol blocks.
