Space-time block coding (STBC) is a recent appealing solution to the problem of exploiting transmit diversity in multi-antenna systems for communications over flat fading channels. In a standard STBC scheme the receiver requires Channel State Information (CSI), which can be acquired via training at...
Block diagram of a MIMO-OFDM system.. We will discuss the design of the encoder and the importance of the interleaver in further sections. As for now, we want to highlight the strong analogy between the input-output relationship over a flat fading MIMO channel (5.3) and the system model ...

We propose a new decoder design scheme applicable to the existing transceiver structure for a space-time block coded (STBC) multiuser (MU) communication system over FF and TSF channels. We analyze the impact of channel time variations on the two known ZF and MMSE decoders; then, the ...

The performance of LDPC-STBC and adaptive LDPC-STBC under Rayleigh fading channel is given through computer simulation. 将低密度校验码(lowdesityparitycodes,LDPC)应用于一种简单的发射分集技术(spacetimeblockcodes,STBC)及自适应STBC,推导出LDPC码在与STBC级联并采用自适应功率分配算法时的译码方法,通过计算机...
The performance of space-time orthogonal block (STOB) codes over slow Rayleigh fading channels and maximum-likelihood (ML) decoding is investigated. Two Bonferroni-type bounds (one upper bound and one lower bound) for the symbol error rate (SER) and bit error rate (BER) of the system are ...
Orthogonal Space-Time Block Code (OSTBC) - Nakagami-m fading channel - Ricean fading channelSpace time block coding is a modulation scheme recently discovered for the transmit an- tenna diversity to combat the effects of wireless fading channels. Using the equivalent Single-Input Single-Output (SI...
In this paper, we derive tight random coding error bounds for non-dispersive 2-D (quadrature) block-fading flat Rician channels with complete channel state information (CSI) available at the receiver. The output from the transmitter is subject to an average power constraint. A comparison with ...
