Residual noise identification for PIM measurement systems using variable low-PIM termination
نویسندگان
چکیده
In this letter, we propose the variable low-PIM termination composed of a voltage-controlled IM-source, fixed attenuator, and linear attenuator. The design method for evaluating PIM-level attenuator is presented in order not to limit range entire termination. It possible maintain performance spite using active whose IM level extremely high. This used dynamic residual noise identification PIM measurement systems by observing saturation value voltage sweep. validity confirmed experiments 2GHz band.

Networked PIM Using PDMS
Personal information management (Pim) is a promising new type of application allowing not only to search a desktop, but to pose complex, structured queries against the data on ones computer. We propose to remove the confines of Pim and make selected data available to a network of peers using peer data management system (Pdms) technology. The result is an application for collaborative informatio...

ness of a multiagent system without the significant complexity and overhead required for interagent communication and negotiation. In contrast to centralized approaches, it does not require managing the large amounts of data that the coordinating process needs to compute a global view. In a PIM, the process moves to the data and may perform computations on the components where the data is local...
متن کاملDH-PIM Employing LMSE Equalisation for Indoor Infrared Diffuse Systems
The performance of dual heard pulse interval modulation (DH-PIM) employing least mean square error equaliser (LMSE) in diffuse infrared indoor environment is presented. The work is based on the ceiling bounce channel model and the Monte Carlos simulation. A 3-tap LMSE equaliser is used and results are compared with unequalised DH-PIM and with DH-PIM employing linear zero forcing equaliser (L-ZF...
متن کاملPIM Definition and Description
Answering the requirement of the Model-Driven Architecture approach, as well as the general needs of engineering process definition, requires to precisely define the content and structure of the different models to be produced at project development time. For each model, the following questions must have an answer: What are its content and its objectives? What are the modelling concepts to be u...
