This contribution is an asymptotic analysis of the algorithms proposed in [1]. The algorithms proposed in [1] treats the problem of time delay estimation in an asynchronous direct-sequence code-division multiple access (DS-CDMA) system in a near-far scenario.

In this paper, we propose a new differential semi-blind spatial-temporal beamforming receiver for asynchronous direct sequence wideband code division multiple access (DS-WCDMA) systems. The new receiver presents improved robustness to phase variations and reduction of the effects of nonlinear distortion.

In this paper, we consider several multiuser demodulation schemes for a direct-sequence code-division multiple access (DS-CDMA) system that provide soft-outputs to enhance single-user soft-decision decoders. First, we derive an optimum soft-output multiuser estimation (OSOME) algorithm for asynchronous CDMA channels with white Gaussian noise (WGN). The algorithmgen-erates a posteriori probabili...

In this paper, two multirate transmission schemes are considered for an asynchronous multicarrier (MC) DS/CDMA system: multicode scheme and multiple processing gain (MPG) scheme. Successive interference canceller (SIC) is applied for the two multirate MC-DS/CDMA systems to cancel multiple access interference (MAI). The bit error rate (BER) of each system is obtained by analysis and simulation i...

the purpose of this study was to evaluate the profitability of hatchery litter recycling into poultry feedstuff supplement. the data were collected in 2011 in 4 provinces, by direct interviewing of all hatcheries which used the hatchery litter drying machine. net present value (npv), benefit-cost ratio (bcr), and internal rate of return (irr) methods were applied for this analysis. in the studi...

We study the feasibility of autonomous transaction execution in systems with asynchronous transaction processing based on epsilon serializability (ESR). The abstract correctness criteria deened by ESR are implemented by techniques such as asynchronous divergence control and asynchronous consistency restoration. Concrete application examples in a distributed environment, such as banking, illustr...
