Differential modulation diversity

چکیده
In this paper, differential modulation diversity (DMD) is introduced. This diversity scheme is based on diagonal signal constellations which have been previously proposed for differential space–time modulation (DSTM). DMD can exploit both space and time diversity and DSTM, which is a pure space diversity scheme, results as a special case. A low– complexity noncoherent receiver originally designed for DSTM is adapted to DMD and the power efficiency of DMD for spatially correlated Rayleigh fading and imperfect interleaving is investigated. Keywords—Differential modulation diversity, transmit diversity, space– time block codes, noncoherent detection.

Differential Modulation Diversity for OFDM
The application of differential modulation diversity (DMD) to orthogonal frequency division multiplexing with multiple transmit and/or receive antennas is considered. Based on diagonal signals originally designed for differential space-time modulation, DMD is used to exploit both space and frequency diversity. At the receiver, low-complexity decision-feedback differential detection without chan...

This paper presents the theoretical analysis for Noncoherent multi-tone code division multiple access (MT-CDMA) system in terms of average bit error rate (BER). The system uses differential binary phase shift keying (DBPSK) modulation and post-detection diversity combining, considering slowly Rician fading and frequency selective channel in the indoor environment.

متن کاملA Receiver for Differential Space-Time π/2-Shifted BPSK Modulation Based on Scalar-MSDD and the EM Algorithm
In this paper, we consider the issue of blind detection of Alamouti-type differential space-time (ST) modulation in static Rayleigh fading channels. We focus our attention on a π/2-shifted BPSK constellation, introducing a novel transformation to the received signal such that this binary ST modulation, which has a second-order transmit diversity, is equivalent to QPSK modulation with second-ord...
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...
