Cooperation diversity techniques will be explored ‚ to obtain better performance for OFDM systems. I. Introduction: Multiple antennas transmitting diversity techniques have been investigated based on their ability to combat fading induced by multi-path of the channel‚ and have been widely used in wireless communication system. However‚ the deployment of antenna array on mobile terminal is difficult due to the size and power limitation. In order to solve this problem‚ a new mode of gaining transmit

War II‚ which saw the development of high-power microwave emitters known as cavity magnetrons‚ the idea of using microwaves to transmit power was researched. In 1964‚ William C. Brown demonstrated a miniature helicopter equipped with a combination antenna and rectifier device called a rectenna. The rectenna converted microwave power into electricity‚ allowing the helicopter to fly. In principle‚ the rectenna is capable of very high conversion efficiencies - over 90% in optimal circumstances. Most proposed

A computer network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet. Network devices that originate‚ route and terminate the data are called network nodes.[1] Nodes can include hostssuch as servers and personal computers‚ as well as networking hardware. Two devices are said to be networked when a process in one
