Differential space-time modulation - coding and capacity results

چکیده
In this paper, powerful coding techniques for differential space-time modulation (DSTM) over Rayleigh flat fading channels and noncoherent demodulation without channel state information at the receiver are investigated. In particular, multilevel coding (MLC), bit-interleaved coded modulation (BICM), and so-called hybrid coded modulation (HCM) are devised and compared using capacity arguments. For improved noncoherent reception multiple-symbol differential detection (MSDD) and a low-complexity version of MSDD are adapted to DSTM.

متن کاملDifferential Space-Time Coding Scheme Using Star Quadrature Amplitude Modulation Method
Differential space-time coding (DSTC) has receivedmuch interest as it obviates the requirement of the channel state information at the receiver while maintaining the desired properties of space-time coding techniques. In this paper, by introducing star quadrature amplitude modulation (star QAM) method, two kinds of multiple amplitudes DSTC schemes are proposed. One is based on differential unit...

متن کاملConcatenated space-time coding
The serial concatenation of standard convolutional codes with differential spacetime modulation is considered for fast flat fading multiple antenna channels. Decoding is performed iteratively by passing symbol-wise a-posteriori probability information between the decoders of the inner space-time code and the outer convolutional code. An input-output extrinsic information transfer analysis is us...

Multiple-input multiple-output (MIMO) wireless communication systems have been studied a lot in the last ten years. They have many promising features like array gain, diversity gain, spatial multiplexing gain, interference reduction, and improved capacity as compared to a single-input single-output (SISO) systems. However, the increasing demand of high data-rate in current wireless communicatio...
