Spread Spectrum Transmission Comparison Introduction to Spread Spectrum Transmission What is it? Why is it important? What issues are addressed? How does it work? Answer - What is it? The various commercial and government users that use satellite communications are relying increasingly on broadband services of advanced technology to support their operations (mobile operations). SST is that communication technology which is generally used for carrying current mobile satellite networks that are well suited for small light weighted antennas. Why is it important? SST is important in today's satellite-industries as it is used to improve network performance by providing more choices to its customers. It could be a best solution highly suitable for network resulting in lower cost and other benefits. Its best properties include its ability to address selectively, its secure from eaves-dropping and its bandwidth sharing capacity. What issues are addressed? The mounting costs for the earth-station equipment & remote terminals. The density of the networks of the spectrum is regulated by bodies such as ITU & FFC. The frequency of a constant subjected signal is bound by catastrophic interference. SST is capable of providing high error rates even when the signals faint. How does it work? SST utilizes wide band-signals which are hard to interpret because they are noise like. There signals are very hard to demodulate & are anti-jam and because of which military is using them. SST is ...
