PPT-Spectrum Measurements and the Impact to Spectrum Sharing

Paul Kolodzy PhD 6 April 2016 1 CSMAC is investigating the challenges associated with spectral measurements for spectrum sharing Moving from nondirectional transmissions at lower frequencies to more . In most cases emphasis on one of these parameters adversely impacts the other two For example the wide resolution bandwidths R W used to achieve fast measurement speeds result in higher noise levels and potentially reduce dynamic range Increasing th 381a and b brPage 4br mt Fig 7381 b Direct sequence spread spectrum receiver Fig7381 b Binary Adder Balanced Modulator Pseudo noise code enerator Transmitted signal st ct Carrier Frequency f Fig 7381 a Direct sequence spread spectrum transmitter mt idle channel selection opportunistic spectrum access,cognitive radios, spectrum agility.1.
