Troposcatter transmission has widely been applied in military and civil fields due to its main advantages such as fast deploying, mobility, high reliability and good security. Thus, we focus on the study of troposphere wireless transmission in this thesis. Orthogonal frequency division multiplexing (OFDM) transforms a frequency-selective channel into a flat fading channel to combat the impact of multi-path fading, and multiple-input and multiple-output (MIMO) significantly improves the performance and transmission speed of wireless systems without increasing system bandwidth. Therefore, combining MIMO and OFDM can greatly improve the performance and transmission speed of troposcatter communication systems in multi-path fading channels.The main research work of this thesis is as follows: MIMO-OFDM systems are introduced, its baseband model is derived, and the character of the troposphere channels is extracted. Under troposphere environments, space-time block codes (STBC) and space-frequency block codes (SFBC) are designed for MIMO-OFDM systems. By simulation, it follows that STBC achieves a better performance over SFBC. Finally, signal detection algorithms including zero-forcing , serial interference cancellation, maximum likelihood, and semi-definite relaxation(SDR)are investigated for MIMO-OFDM systems in troposphere channels. From simulation, SDR makes a good compromise between complexity and performance compared with other algorithms.

The Heart
A person who wants to carry out his own dream must work with his heart. Whatever one does without showing his feelings won't be perfect. Just get ralph lauren polo shirts!But when you enjoy what you do, you want it to be wonderful. For instance, if a singer does not like music and he sings songs just to make money, the audience won't pay attention to him. Here is the best northface outlet!Whereas, if a musician writes music just for fun and is lost in doing so, his music can appeal to a lot of people. This is your favorit chi hair straightener!It isn't hard for him to become famous. Besides, a painter can't paint pictures that resemble fantastic natural wonders if he can't be immersed in what he sees. Also, girlfriends will break up with their boyfriends if they can't feel the love of their boyfriends. Believe it or not! So we should all do things with all of our hearts to succeed!

Earthquakes
Earthquakes may take place anywhere on the earth’s surface. During all earth quake, the vibrations make the earth’s surface tremble, and even crack open.Do you like those cheap men's nike shoes? Houses fall, people are lilled or injured and sometimes whole cities are destroyed.
Can we do something to protect ourselves against earthquakes?I love northface jackets. Can we take precau tionary measures? We can. Scientists have made investigation on earthquakes. They have made maps showing the “earthquake belts”.You can buy cheap north face jackets here. In areas along these belts, earthquakes are likely to occur. In these areas we can build special houses to resist earthquake shocks and protect ourselves.
in the future, scientists will be able to predict exactly when and where earthquakes will take place. Then they will be able to tell people to take precautionary measures. Thus lives can he saved and damage can be lessened.
