Amateur spread spectrum allowed

Spread Spectrum Scene. Back in , the RF world got very excited about the possibilities of using spread spectrum for ham radio. Listed below is some historical information related to this movement -- FCC's initial proposed regulations that would make this possible, and comments from the community about these proposed regulations.

FCC Adopts Spread Spectrum Rules Changes

N4ICK became involved later, beginning in These restrictions have been the subject of controversy within the Amateur Radio community ever since, some desiring to remove them entirely including permitting spread spectrum operation on all amateur bands, others wishing to tighten them. Spread spectrum is a technique to reduce the power density of a radio transmission by spreading its signal over a wide band of frequencies, at least 10 times the information rate and usually much higher. Under some conditions, reduction of power density permits greater spectrum sharing opportunities than using the traditional access method frequency- division multiple access FDMA or even time-division multiple access TDMA. As the receiving system must despread the spread spectrum signal just the opposite from how it was originally spread and in exact synchronization, there is the added advantage of rejection of interference or jamming and immunity from frequency-selective fading. Some modern cellular and other systems use a form of spread spectrum called code-division multiple access CDMA.

(E8D03) Spread Spectrum

In telecommunication and radio communication , spread-spectrum techniques are methods by which a signal e. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference , noise , and jamming , to prevent detection, to limit power flux density e. Spread spectrum generally makes use of a sequential noise -like signal structure to spread the normally narrowband information signal over a relatively wideband radio band of frequencies. The receiver correlates the received signals to retrieve the original information signal. Originally there were two motivations: either to resist enemy efforts to jam the communications anti-jam, or AJ , or to hide the fact that communication was even taking place, sometimes called low probability of intercept LPI.

Spread spectrum SS uses a wide bandwidth which would cause too much crowding on the relatively narrow bands below UHF. Last edited by wileyj Register to edit. Tags: arrl chapter 3 arrl module 3d.

    Der Plot ist so schlecht, da ist ja Stroh auf dem Boden noch Logischer.
