Peak Power Reduction in Multicarrier Waveforms
Modern wireless communication systems employ multicarrier waveforms, such as the widely-used Orthogonal Frequency Division Multiplexing (OFDM) and the recent OFDM with Offset-QAM (OFDM/OQAM) schemes. An inherent characteristic ...
DNS-based Authentication of Named Entities
Public Key Infrastructure (PKI) has turned out to be useful when two parties negotiate about a shared secret in order to establish an encrypted connection between them. To verify the public key, a certificate is used. The ...
NLOS mitigation techniques in GNSS receivers based on Level Crossing Rates (LCR) of correlation outputs
Global Navigation Satellite Systems (GNSS) provide navigation services with a highly precise estimation of the position. First military influenced, the use of satellite-based positioning has gained a lot of interest also ...
Evaluation of focus curves based on goodness criteria
In smartphones there are restrictions for imaging systems like computation capabilities, power and physical size, which have caused usage of relatively low quality camera sensors and modules. To achieve acceptable image ...
