摘要：
An MPEG-4 based Space-Time (ST) coded Orthogonal Frequency Division Multiplexing (OFDM) audio transceiver is proposed. The high-quality MPEG-4 audio codec is operated at bit rates between 16 and 64 kbit/s per channel and combined with turbo channel codes as well as space time codes. As expected, the space-time coding scheme, using two transmitters and one receiver outperformed the conventional one transmitter, one receiver arrangement by about 4dB in channel SNR terms, when maintaining an error-free audio quality.
