We developed a method that analyzes the quality of the cultivated cropland class mapped in the USA National Land Cover Database (NLCD) 2006. The method integrates multiple geospatial datasets and a Multi Index Integrated Change Analysis (MIICA) change detection method that captures spectral changes to identify the spatial distribution and magnitude of potential commission and omission errors fo...

-A new code for Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) is proposed and is called Flexible Cross-correlation (FCC) code. The FCC code possesses various advantages; including easy code construction using Tridiagonal matrix compared to other SAC-OCDMA codes such as MDW, MQC and MFH, shorter code length and the important properties of this code is the flexible c...

This paper studies the application of the Minimum Mean Square Error beamformer to OFDM-based Wireless LANs. The questions here addressed are mainly the design with finite-length data and the choice of the OFDM signal domain where the beamformer is applied, either frequency or time. As OFDM signals need more samples than other modulations to stabilize the estimations of the signal statistics, ho...

This paper presents a feasibility study of DC offset filtering for direct-conversion UTRA-FDD/WCDMA receivers. Spectral characteristics and properties of continuous transmission facilitate the use of simple high-pass filtering and this method is evaluated in the paper. Design equations for DC offset power to down-converted signal power ratio are presented and the impact on bit error rate of hig...

This paper focuses on the BER, Q-Factor, Eye Height for a four user OCDMA with varying jitter. Performance of the OCDMA communication system has been evaluated in terms of bit error rate, Q-factor and eye closure with jitter varying from 0 Unit-Interval to 0.7 Unit-Interval in steps of 0.1 Unit-Interval. Simulations were carried out using commercially available simulator from Gigasoft, OPTIWAVE.

From earlier chapters, we recall the performance of digital communication systems to be evaluated by bit error rate (BER). Influenced by the development of modern probability theory and statistical decision theory, communication theory has been developed to evaluate the performance of digital communication systems and to design more effective systems meeting the need from engineering. The first...

In this paper, we derive an analytical expression for the packet error probability in a telecommunication scheme with the three-copy majority combining. The derived expression has a closed form and it is applicable in the case of diversity packet transmission over three independent binary symmetric channels with various bit error probabilities. This expression is then used to analyze an example...
