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.
