During the design, it is important to evaluate user experience of representative users in many human product interactions. But, some cases, difficult or even impossible recruit because they have disabilities that do not allow them take part such investigations. Thus, alternative populations are widely studied. The most common way replace real blind people use sighted but blindfolded when studyi...

The next-generation navigation tools are developed to enable precision and reliability. Military users more likely encounter jamming, so it is necessary seek the technologies which can steadily provide high-precision positioning services in all-weather harsh conditions. However, when use an array antenna for interference suppression, usually introduces pseudorange carrier phase biases, deterior...

CogWave is a free and open-source software platform aiming at developing cognitive radio waveforms. Combining CogWave with USRP gives a rapid prototyping platform for physical layer design and algorithm validation through a realtime video, audio and text transmission. This paper presents the cognitive blind orthogonal frequency division multiplexing (OFDM) waveform implemented in the CogWave so...
