Low soil fertility is one of the factors most limiting agricultural production, with phosphorus deficiency being among the main factors, particularly in developing countries. To deal with such environmental constraints, remote sensing measurements can be used to rapidly assess crop performance and to phenotype a large number of plots in a rapid and cost-effective way. We evaluated the performan...

A low-cost rapid-prototyping system using Texas Instruments' (TI) TMS320C30 Evaluation Module (EVM) based on the MathWorks' development software is presented in this paper. The rapid prototyping system serves as an educational tool in learning digital signal processing (DSP) and seeing the concept realized in real time. The development software modules, Simulink, uses graphical block diagrams t...

The Java Virtual Machine Language (JVML) is rapidly emerging as the de-facto standard for representing portable code and Java Virtual Machines (JVMs) are increasingly being used as standard platforms for running applications. But how suitable are the JVMs and the associated JVML for this purpose? This paper argues that JVML has a serious drawback in that it is not extensible enough. This lack o...

This paper presents the estimation of bit error ratio (BER) from error vector magnitude (EVM) for M-ary quadrature amplitude modulation (QAM) formats in optical coherent systems employing carrier phase recovery with differential decoding to compensate for laser phase noise. Simulation results show that the relationship to estimate BER from EVM analysis for data-aided reception can also be appli...

To gratify the requirements of modern wireless communication, linearization of power amplifier (PA) becomes a foremost research field. Several linearization techniques have been introduced time to time. Digital pre-distortion linearization technique is the best linearization technique from other linearization techniques. In this paper, modified memory polynomial function is used to model PA and...

Smart video analytics algorithms can be embedded within surveillance sensors for fast in-camera processing. This paper presents a DSP embedded video analytics system for object and people tracking, using a PTZ camera. The tracking algorithm is based on adaptive template matching and it employs a novel Sum of Weighted Absolute Differences. The video analytics is implemented on the DSP board DM64...

In this paper, we performed DTV interference test in order to measure the affected ranges of DTV service due to the operating of narrowband system as the DTV White Space Service in Korea. The Terrestrial Truncated Radio (TETRA) system was targeted as a narrowband application of DTV White Space. A series of simulations was conducted in order to estimate the effective ranges according to the oper...

Performance of millimeter-wave (mm-wave) multiband orthogonal frequency division multiplexing (MB-OFDM) ultrawideband (UWB) signal generation using frequency quadrupling technique and transmission over fiber is experimentally investigated. The frequency quadrupling is achived by using only one MachZehnder modulator (MZM) that is biased at maximum transmission (MATB) point. At the output, a freq...

The complete error-in-variables-model (EVM) framework, consisting of both design of experiments and parameter estimation stages, is applied to the terpolymerization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS, M1), acrylamide (AAm, M2) and acrylic acid (AAc, M3). This water-soluble terpolymer has potential for applications in enhanced oil recovery, but the associated terpolymerization k...
