On the Systematic Measurement Matrix for Compressed Sensing in the Presence of Gross Errors
Inspired by syndrome source coding using linear error-correcting codes, we explore a new form of measurement matrix for compressed sensing. The proposed matrix is constructed in t...

On the achievable throughput of CSMA under imperfect carrier sensing
Abstract—Recently, it has been shown that a simple, distributed CSMA algorithm is throughput-optimal. However, throughput-optimality is established under the perfect or ideal car...

Sensitivity of Spectrum Sensing Techniques to RF Impairments
Cognitive radios are devices capable of sensing a large range of frequencies in order to detect the presence of primary networks and reuse their bands when they are not occupied. D...

Para-social Presence: A Re-conceptualization of 'Social Presence' to Capture the Relationship between a Web Site and Her Visitor
The primary purpose of this paper is to describe the theoretical underpinnings of the construct Para-social Presence (PSP). Para-social presence refers to the extent to which a me...
