In today\'s world, wireless communication systemsbased on frequency modulation (FM) and code division multiple access (CDMA)are the primary means of communication for mobile phones and other devices. However, the transmission of signals across distances in these systems can be severely limited due to interference from geographical features such as mountains or by the use of directional antennas. To overcome these obstacles, the use of multiple antenna systems has become increasingly common.

A DMB-SMART Antenna system is a type of multiple antenna system designed to increase the coverage range of various signals, including those used for wireless communication. In essence, the DMB-SMART antenna utilizes a series of small "smart" antennas that are placed in different locations and communicate with each other to optimize signal strength and coverage. This system is not only more efficient than traditional single-antenna systems, but it can also provide increased signal strength and better coverage over longer distances.

The working principles of DMB-SMART antenna systems are based on the concept of distributed antenna systems. In a distributed anntena system, multiple antennas are connected together in a distributed manner, allowing for maximum coverage of the area of interest. By using distributed antenna systems, the areas where the signals are weakest can be extended, while also eliminating the need for additional antennas or repeaters in order to extend the coverage range.

When it comes to applications, a DMB-SMART antenna system can be used for a variety of communication systems, including broadcast, point-to-point, and vehicle-to-vehicle systems. In broadcast applications, these schemes are often used to extend the coverage of a given broadcast signal, allowing for a larger coverage area. Additionally, the system can also be used for point-to-point systems, as well as for vehicle-to-vehicle communication, where the signal needs to be transmitted across much greater distances.

In terms of RF evaluation and development, DMB-SMART antenna systems can be extremely useful tools. By using these systems, engineers can quickly and accurately determine how a particular signal is behaving in a given environment, allowing them to identify possible issues and improve the signal quality. Additionally, these systems can also be used to simulate a variety of different radio environments, allowing engineers to properly evaluate the performance of different antenna systems under varying conditions.

Overall, DMB-SMART antenna systems are an extremely useful tool for improving the coverage and signal quality of various wireless communication systems. By using distributed antenna systems, engineers can identify and eliminate coverage gaps, while also increasing the overall coverage range. Additionally, these systems can also be used for RF evaluation and development, allowing engineers to quickly and accurately assess the performance of different antenna systems under a variety of conditions.
