Differential space-time block codes
We propose a new differential modulation scheme for multiple-antenna systems based on square spacetime block codes (STBC) when neither the transmitter nor the receiver knows channel state information. Compared with the known differential unitary space-time modulation (DUSTM), the proposed constellations generally have multiple amplitudes and do not have group properties. This generalization pot...
متن کاملDifferential Space Time Block Codes Using Nonconstant Modulus Constellations for Four Transmit Antennas
We propose differential space time block codes (STBC) using nonconstant modulus constellations, e.g., quadrature amplitude modulation (QAM), which cannot be utilized in the conventional differential STBC. Since QAM constellations have a larger minimum distance compared with the phase shift keying (PSK), the proposed method has the advantage of signal-to-noise ratio (SNR) gain compared with conv...
متن کاملFast Multiple–Symbol Differential Detection for Unitary Space–Time Modulation
Unitary differential space–time modulation (UDSTM) where unitary matrix symbols are differentially encoded prior to transmission is an attractive solution for transmission over multiple–input multiple–output (MIMO) fading channels without requiring channel state information (CSI). In this work we investigate and optimize the application of tree–search algorithms to maximum–likelihood multiple–s...

متن کاملSymbol Error Probability of Orthogonal Space-Time Block Codes with QAM in Slow Rayleigh Fading Channel∗
In this paper, using the exact expression for the pairwise error probability derived in terms of the message symbol distance between two message vectors rather than the codeword symbol distance between two transmitted codeword matrices, the exact closed form expressions for the symbol error probability of any linear orthogonal space-time block codes in slow Rayleigh fading channel are derived f...
