A novel joint blind channel estimation and turbo equalization algorithm is proposed for orthogonal frequency-division multiplexing (OFDM) system in this paper. It has been proved that, blind channel estimation based on linear precoding can obtain channel information exactly. However, the precoding will cause inter-symbol interference (ISI). With the existence of ISI, the bit error rate (BER) performance...
This article at first introduces the development of the channel coding technology driven by the Shannon's theory, and the tendency that the coding and modulation will be combined. Then it elaborates on the channel coding problems under the wireless channel. At last it discusses the development direction of the coding technology, that is, when considering the specific wireless communication environment,...
In this paper, a joint detection and decoding algorithm is proposed for the spatial multiplex multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) channels. In the spatial multiplexed MIMO-OFDM channels, if enough cyclic prefix (CP) at least equal to the channel length is used, inter symbol interference is completely canceled and consequently spatial multiplexing...
