The block diagram of the QAM simulation model is as shown below,
Code for MATLAB clear;

For QAM, each carrier is ASK modulated. The two independent signals are simultaneously transmitted and at the receiver, the two signals are demodulated, and the results combined to produce the original binary input.…

In other words, the sequences transmitted from two different antenna elements are orthogonal to each other for each transmission block. For real signal, it is possible to reach full rate. However, it has been proven in [4] that this statement is false for two-dimensional constellations, complex signals. The encoding and decoding approaches follow the pattern described in Alamouti’s method. For complex signals, the theory of orthogonal designs can be used to generate coding matrices that achieve a transmission rate of 1/2 for the cases of 3 and 4 transmission…
3) Between -7999 and +7999. This is because 16 bits provide four four-bit locations. The lowest (right most) and two middle 4 bits can each store any number from 0 to 9. In the highest (left most) 4 bits, one bit is used for the sign, leaving 3 bits for digits. These 3 bits can accommodate numbers between 0 and 7.…
The bit pattern 1011 in 1’s complement notation is 7. The result of 7 – 2 using 2’s complement notation is 8. The bit pattern 1110 in 2’s complement notation is 9. The range of numbers that can be represented using the Excess-2N-1 notation is _________.…

Animals fight for survival daily, and sometimes their lives depend on their ability to adapt with their surrounding environments. Natural Selection is the process in which individuals have certain traits that allow them to survive and produce more efficiently (Reece et al.456). The animals that inherit these important traits have a higher fitness; therefore, those without the traits have a lower fitness (Reece et al.456). One example of natural selection is the differences between American Alligator and Albino alligator. The American Alligator acquired dark, thick skin due to the swampy, wet marshlands they live in ("American Alligator." Aquatic Community. AC Tropical Fish and Aquarium. Web. 21 Feb 2013.). It has a higher fitness than the Albino Alligator because their pigment not only hides them from predators, but also gives them an upper hand when sneaking up on prey while hunting ("American Alligator." Aquatic Community. AC Tropical Fish and Aquarium. Web. 21 Feb. 2013.). On the other hand, the Albino Alligator has a much lower fitness and is very rare because it does not have the allele that produces the pigment that has dark skin. The white color stands out like a sore thumb in its dark environment ("White alligator is one of the rarest in the world." Telegraph Media Group. 16 Feb 2009: n. page. Web. 21 Feb. 2013.).…
As you can see, these abbreviations stand for a specific number of bytes. And each byte holds 8 bits capable of forming 256 combinations of 1/0. Wow!…
Over the years the Music culture has changed rapidly. “Rock and roll changed to psychedelic, disco to heavy metal and punk rock to soft rock”. Today it seems that Hip hop and music has become a big sensation of our era. We have also been influenced by not only hip hop but also in reggae music which originated from a small Caribbean island called Jamaica. A very inspirational man amounted from here, a man whose legacy that will live on for generations to come. Robert Nesta Marley known to us as Bob Marley has changed our world forever. His inspirational speaking about social change pertaining to his music was used to unite the people. His music was to help promote freedom, peace, reconciliation, and equal rights for all. (-emily)…
We as a group of telecommunication engineer in the established telecommunication company have been invited to participate in one seminar called “Principle Communication and Communication System”. In the seminar, our group has been responsibilities on a project to design a balanced ring modulator circuit which is need to comes up with proposal and present it in a technical report.…
