With the rapid growth of multimedia services, future generations of cellular communications require higher data rates and a more reliable transmission link while keeping satisfactory quality of service. In this respect, multiple input multiple-output (MIMO) antenna systems have been considered as an efficient approach to address these demands by offering significant multiplexing and diversity gains over single antenna systems without increasing requirements on radio resources such as bandwidth and power. Although MIMO systems can unfold their huge benefit in cellular base stations, they may...

There will be automatic track switching and continuous monitoring of trains. When the two trains are on the same track and there is a chance of collision the train will be shifted to next track automatically. It is only possible when we continuously monitor the status of the trains. It could be a reliable solution for railway authorities, by consuming low cost and above all will decrease the chances of accidents, which we all think is a great achievement.
