This paper presents a recently developed particle simulation code package PIFE-PIC, which is novel three-dimensional (3-D) parallel immersed finite element (IFE) particle-in-cell (PIC) model for simulations of plasma-material interactions. framework based on the nonhomogeneous electrostatic IFE-PIC algorithm, designed to handle complex interface conditions associated with irregular geometries u...

The performance of direct-sequence spread-spectrum (DS/SS) in packet radio networks suffers from the nearfar problem. This can be mitigated by the use of multiuser receivers. This paper introduces a model for peer to peer communications using a simple parallel interference cancellation (PIC) technique, which requires cancellation of only a few dominant interferers. The system performance is eva...

In the parallel signal processing, the multi-user detection precision of parallel interference cancellation (PIC) detector is always easily affected by the decision error diffusion. Based on the fast convergence and low complexity of blind adaptive Kalman algorithm, a new blind adaptive Kalman-PIC (KPIC) multi-user detection (MUD) algorithm is proposed for the direct sequence spread spectrum co...

PIC method of plasma simulation is widely used in plasma physics research because of its ability to solve wide range of problems in kinetic approach. Regarding to description of PIC method we refer to [Birdsall et al., 1995]. This work is focused on PIC simulations of dc discharge in cylindrical magnetron device. Magnetrons are used in industry e.g. for thin film layer coating and etching. Many...

Abstract—Partial interference cancellation (PIC) group decoding proposed by Guo and Xia is an attractive low-complexity alternative to the optimal processing for multiple-input multipleoutput (MIMO) wireless communications. It can well deal with the tradeoff among rate, diversity and complexity of spacetime block codes (STBC). In this paper, a systematic design of full-diversity STBC with low-c...

The physical processes of charge collection and gas multiplication of a Micro Pixel Chamber (μ-PIC) were studied in detail using a three-dimensional simulation. The collection efficiencies of primary electrons and gas multiplication factors were calculated for several electrode structures. Based on those studies, we analyzed the optimization of the electrode structure of the μ-PIC, in order to ...

Existing models have developed computational Hall thruster codes to a level where qualitative features of the plasma and electric field can be reproduced. These results are possible only with the use of corrections to various transport and energy parameters; however, these corrections are not rigorously defined by the actual physics governing these processes. This paper presents a 2-D hybrid PI...
