Using cofdm transmitter in a drone

  1. 1. Using COFDM Transmitter In A Drone The Importance of COFDM Transmission The expanded form of COFDM is Coded Orthogonal Frequency Division Multiplexing. COFDM is a scheme of modulation that is used to divide one digital signal across a thousand or even more signal carriers simultaneously. All these signals are sent at 90 degrees to each other so that these do not interfere with one another. COFDM transmission is mainly used in Europe and therefore a COFDM transmitter- receiver is relevant in that continent. COFDM is also supported by the pertinent standards of broadcasting (Digital Video Broadcasting) in the US.
  2. 2. Application of COFDM in Drones The reason why Europe decided upon using COFDM transmission is that this form of transmission can overcome the effects of multipath. A normal signal transmission encounters numerous obstacles. These obstacles can be buildings and even people and they result in scattering the signal into multiple paths. When these multiple signals reach the TV, the scattered elements of the signal often cause what is known as ghost images. COFDM resists multipath effects since it transmits the same signal using multiple carriers. The effect is that of the signal flowing around the obstacle thereby making this transmission very effective. There are premier providers of drones for government applications with an emphasis on public safety missions to include Search and Rescue, Crime Scene Surveys and tactical response surveillance. The payload options include diverse thermal IR cameras, live video downlinks, encrypted data-links and wireless mesh besides long range COFDM transmitter- receiver systems.
  3. 3. Long Range Transmission Today drones offer high grade wireless video systems that are built with the needs of law enforcement agencies in mind. These systems give the officers of law enforcement agencies the tactically superior range and non-line-of-sight performance that is necessary in today’s missions. The technology offered therefore includes legacy analog, COFDM transmitter- receiver and Agile Mesh brand systems. The COFDM transmitters and receivers are well suited for UAV as well as mobile cameras, vehicles and broadcast cameras besides the use of the military and the police. The transmitters and receivers are custom- made adaptable to different applications. Some of the transmitters are the size of a credit card with a thickness of about 1” and they weigh less than 170gm. This increases their application for the UAV or drone that needs a video downlink system that is very light in weight and small in size. Technology permits the use of a number of these COFDM transmitters and receivers in the same area.
