Position estimation in indoor localization system [PDF]
Indoor positioning systems can be used for many applications such as indoor navigation,emergence response, asset monitoring, and shopper assistance. Due to the weak received signal and multipath reflection, the global positioning system (GPS) generally ...

Covariance matrix estimation with heterogeneous samples [PDF]
, 2008 We consider the problem of estimating the covariance matrix Mp of an observation vector, using heterogeneous training samples, i.e., samples whose covariance matrices are not exactly Mp.

Investigation of Blanking Nonlinearity in OFDM Systems [PDF]
, 2011 In this paper, we analyze the influence of a blanking nonlinearity onto OFDM systems in detail. We will derive closedform expressions for the signal degradation and the interference, which is introduced by the blanking nonlinearity.

On the Achievable Rates for the Return-Link of Multi-Beam Satellite Systems Using Successive Interference Cancellation [PDF]
, 2011 This paper investigates the theoretically reachable rates in the return-link of multi-user multi-beam satellite systems. The return-link can actually be analyzed by means of multiple-input multiple-output signal processing techniques. While MIMO inspired

Cross-layer interference mitigation for cognitive radio MIMO systems [PDF]
, 2011 In this paper, we investigate the interference mitigation from a cross-layer perspective for a cognitive radio (CR) multiple-input multiple-output (MIMO) network coexisting with a primary time-division-duplexing (TDD) system.

Movement of pond-breeding amphibians in fragmented landscapes : responses of great crested newt (Triturus cristatus) to road mitigation [PDF]
, 2017 With the increase of transportation system in the world, roads facilitate opportunities for human social and economic development. Roads are also the primary cause of multiple and diverse negative ecological effects.
