However, a limitation of this system is that a line of sight to multiple satellites is required; therefore, it is unsuitable to use indoors or in urban canyons. Also, in the presence of radio-frequency interference or jamming, GPS may be unavailable. Alternative methods of navigation and positioning are need to either compliment GPS as a backup or for use in areas unreachable by satellites. This research analyzes a feature-based correlation approach for determining reception differences between two Orthogonal Frequency Division receivers for the purpose of TDOA calculations. Multicarrier signals have a very defined signal structure which allows for non-cooperative symbol detection techniques. Simulations are conducted with different correlation windows sizes, SNR values, and eight different statistical features.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":51963660206368,"sku":"NEW1288368909","price":19.14,"currency_code":"USD","in_stock":true}],"url":"https:\/\/miakarts.com\/products\/navigation-using-orthogonal-frequency-division-multiplexed-signals-of-opportunity-1288368909","provider":"Miakarts Books","version":"1.0","type":"link"}
