An efficient joint channel estimation and decoding algorithm for turbo-coded space-time orthogonal frequency division multiplexing receivers
(Inst Engineering Technology-IET, 2008)
The challenging problem in the design of digital receivers of today's and future high-speed high data-rate wireless communication systems is to implement the optimal decoding and channel estimation processes jointly in a ...
MAP channel-estimation-based PIC receiver for downlink MC-CDMA systems
(Hindawi Publishing Corporation, 2008)
We propose a joint MAP channel estimation and data detection technique based on the expectation maximization (EM) method with paralel interference cancelation (PIC) for downlink multicarrier (MC) code division multiple ...
Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
(Wiley-Blackwell, 2008)
In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ...
Anterior instrumentation for adolescent idiopathic scoliosis
(Springer Verlag, 2001)
Thirty-two patients with adolescent idiopathic scoliosis underwent anterior fusion with rigid single rod (third generation instrumentation) and titanium mesh cages. The mean follow-up was 31 (24-45) months and the mean age ...
The evaluation of microbial contamination in platelet concentrates prepared by two different methods
(Pergamon-Elsevier Science Ltd, 2001)
The microbial contamination of platelet concentrates (PCs) prepared by two different methods both with a high risk of bacterial contamination during preparation and storage were evaluated. For apheresis platelets the ...
The stability constants of the rare earth complexes with trimetaphosphoric acid
(Soc Chimica Italiana, 2001)
The stability constants of the complexes formed between the rare earth metal ions and the anion of trimetaphosphoric acid have been determined at a temperature of 20 degreesC and an ionic strength of mu =0.1 by the ...
Removal of UroLume endoprosthesis using holmium : YAG laser
(Mary Ann Liebert Inc Publ, 2001)
A potential complication of UroLume endoprosthesis is migration which may necessitate removal of the stent. Stent removal may be associated with complications such as urethral injury bleeding and external sphincter trauma. ...
Long-standing seroma after ultrasound-assisted liposuction
(Lippincott Williams & Wilkins, 2001)
[Abstract Not Available]
Going against the national cultural grain: a longitudinal case study of organizational culture change in Turkish higher education
(Carfax Publishing, 2000)
This paper presents results of a longitudinal case study inquiry into the measurement of organizational culture change through the implementation of total quality management (TQM) concepts in a higher education context. ...
Unconditional maximum likelihood approach for localization of near-field sources in 3-D space
(IEEE, 2004)
Since maximum likelihood (ML) approaches have better resolution performance than the conventional localization methods in the presence of less number and highly correlated source signal samples and low signal to noise ...
