Differential Lattice Decoding in Noncoherent MIMO Communication
نویسندگان
چکیده
We present improved differential lattice decoding (DLD) for multi-antenna differential modulation by exploiting both basis reduction and sphere decoding. The extra complexity of DLD is shown to be worthwhile in terms of the obtained performance gain over Clarkson et al.’s decoding scheme. With roughly another fold of complexity of basis reduction, DLD augmented by a local search practically attains the maximumlikelihood decoding performance. Index TermsBasis reduction, differential modulation, multiantenna communication, sphere decoding, universal lattice decoding.

Lattice-Based Precoding And Decoding in MIMO Fading Systems
In this thesis, different aspects of lattice-based precoding and decoding for the transmission of digital and analog data over MIMO fading channels are investigated: 1) Lattice-based precoding in MIMO broadcast systems: A new viewpoint for adopting the lattice reduction in communication over MIMO broadcast channels is introduced. Lattice basis reduction helps us to reduce the average transmitte...
متن کاملNoncoherent Decision-Feedback Equalization in Massive MIMO Systems
In this paper, a noncoherent approach to decisionfeedback equalization (DFE) in multi-user massive MIMO systems is presented. Thereby, the contradicting principles of DFE, where interference of already detected symbols is canceled using actual channel knowledge, and noncoherent reception, where the symbols are detected without any channel-state information, are combined. Based on an analysis of...
متن کاملGrassmannian Packings From Operator Reed-Muller Codes
This paper introduces multidimensional generalizations of binary Reed–Muller codes where the codewords are projection operators, and the corresponding subspaces are widely separated with respect to the chordal distance on Grassmannian space. Parameters of these Grassmannian packings are derived and a low complexity decoding algorithm is developed by modifying standard decoding algorithms for bi...
متن کاملLattice Reduction-Aided Detection for Overloaded MIMO Using Slab Decoding
In this paper, we propose an overloaded multiple-input multiple-output (MIMO) signal detection scheme with slab decoding and lattice reduction (LR). The proposed scheme firstly splits the transmitted signal vector into two parts, the post-voting vector composed of the same number of signal elements as that of receive antennas, and the pre-voting vector composed of the remaining elements. Second...
متن کاملUnified MIMO-Multicarrier Designs: A Space-Time Shift Keying Approach
A survey and tutorial is provided on the subject of multiple-input–multiple-output (MIMO) multicarrier (MC) systems relying on the space–time shift keying (STSK) concept. We commence with a brief review of the family of MIMO systems, which is followed by the design of STSK systems in the context of MC modulation-based transmissions over dispersive wireless channels. Specifically, the STSK schem...
