QPSK differential space time coding on different unitary matrices sets and initializations

چکیده
This letter investigates a distinct set of complex unitary matrices for differential space time coding by using QPSK modulation. The numerical results show that the properly selection of the initial transmission matrix and the set of unitary matrices can efficiently improve the bit error rate (BER) performance, especially for the antennas correlated fading channel. The computer simulations are evaluated over slow and fast Rayleigh fading channels. key words: space time coding, unitary matrices, QPSK, Rayleigh fading

Performance Analysis & Implementation of different Modulation Techniques in Almouti MIMO Scheme with Rayleigh Channel
This paper presents performance comparison of various modulation techniques in almouti scheme with Rayleigh fading channel. In the comparison, the space time coding has been used. The performance comparison are made on the basis of symbol error rate(SER) performance matrices over Rayleigh fading channel with 16-PSK,QPSK,PAM,16-QAM,64-QAM modulation technique. The comparison results show that in...
متن کاملBounding Rate and Performance of Differential Unitary Space-Time Codes Using Integral Geometry Measures
We consider lower bounding the maximum achievable rate of a differential unitary spacetime transmission subject to a prescribed performance. We characterize the performance using a suitably defined distance between two unitary matrices, which was previously obtained through pairwise error probability analysis. Considering the set of all unitary or orthogonal matrices as a compact manifold with ...
متن کاملFull diversity sets of unitary matrices from orthogonal sets of idempotents
Orthogonal sets of idempotents are used to design sets of unitary matrices, known as constellations, such that the modulus of the determinant of the difference of any two distinct elements is greater than 0. It is shown that unitary matrices in general are derived from orthogonal sets of idempotents reducing the design problem to a construction problem of unitary matrices from such sets. The qu...
متن کاملSpace-Time Code Design and Its Applications in Wireless Networks
This thesis has two main contributions: the designs of differential/non-differential unitary spacetime codes for multiple-antenna systems and the analysis of the diversity gain when using spacetime coding among nodes in wireless networks. Capacity has long been a bottleneck in wireless communications. Recently, multiple-antenna techniques have been used in wireless communications to combat the ...
متن کاملA New Code for High-Rate Differential Space-Time Coding
In [1], a differential space-time modulation scheme (based on unitary matrices) are presented that can be used without knowledge of the Channel State Information (CSI) at the receiver. This is suitable for mobile communication applications where fading coefficients change rapidly with time. All previous differential space-time codes have been designed to produce full diversity. However, by sacr...
