Coherent versus non-coherent space-time shift keying for co-located and distributed MIMO systems
… systems using both coherent and non-coherent detection. Furthermore, we conceive new serially-concatenated turbo-coding assisted STSK arrangements for the sake of approaching the channel capacity limit, which are designed with the aid of EXtrinsic Information Transfer (EXIT) …

Transmission and detection for space-time block coding and v-blast systems
… focuses on topics of data transmission and detection of space -time block codes (STBC). The STBCs can be divided into two main categories, namely, the orthogonal space-time block codes (OSTBC) and the quasi-orthogonal space-time codes (Q-OSTBC). The space-time block coded systems from …

A framework for low-complexity iterative interference cancellation in communication systems
… dramatically increases the complexity of exact ML detection, we develop iterated-decision detection to mitigate this complexity problem. Iterated-decision detectors use optimized multipass algorithms to successively cancel interference from r and generate symbol

Performance Analysis of Decode-and-Forward Protocols in Unidirectional and Bidirectional Cooperative Diversity Networks
… of a DF protocol with maximum-likelihood (ML) detection. Closed-form approximate average BER expressions involving only elementary functions are presented for a cooperative diversity network with one or two relays. The proposed BER expressions are valid for both coherent and non-coherent …

A likelihood ratio analysis of digital phase modulation
… the theoretical basis for maximum likelihood (ML) detection in coherent digital communication systems, it has not been applied directly to the problem of designing good trellis-coded modulation (TOM) schemes. The remarkably simple optimal receiver of minimum shift keying (MSK) has been shown to …

Blind Acquisition of Short Burst with Per-Survivor Processing (PSP)
… use of Maximum Likelihood Sequence Estimation (MLSE) in the presence of unknown channel parameters. MLSE is a fundamental problem that is closely related to many modern research areas like Space-Time Coding, Overloaded Array Processing and Multi-User Detection. Per-Survivor Processing (PSP) is a …

Near-capacity co-located and distributed MIMO systems
… on Generalized Multi-Layer Space-Time Codes (GMLST), which may be viewed as a composite of V-BLAST and STC, hence they provide both multiplexing and diversity gains. The basic decoding procedure conceived for our GMLST arrangement is a certain ordered successive decoding scheme, which combines …
