Comparative study of concatenated turbo coded and space-time block coded as well as space-time trellis coded OFDM

摘要

Space-time block codes provide substantial diversity advantages for multiple transmit antenna systems at a low decoding complexity. In this study, we concatenate both space-time block and trellis codes with turbo convolutional (TC) coded orthogonal frequency division multiplexing (OFDM) for achieving a high coding gain. The associated performance and complexity of the coded OFDM schemes is compared.
