Feedback Effect for Wireless High-power Transmission
نویسنده
چکیده
Wireless power transmission is based on electromagnetical phenomenon between two separate coils. In order to transfer power from one to the other, we have to cause a time-varying current along one coil. Many of conventional wireless power transmission systems suppose a sinusoidal current of the coil. One reason for it could be the convenience that we have a sinusoidal power source as the industry standard. If we can use a power source which generates many types of wave form, we do not necessarily use the sinusoidal wave. In this study, we propose to add a feedback signal on a sinusoidal signal, that is, we propose to utilize a non-sinusoidal input. We will evaluate the sinusoidal wave and non-sinusoidal wave from the viewpoint of transmission power and efficiency to secondary side. Key–Words: wireless power transmission, non-sinusoidal input, feedback

Performance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection
In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...

متن کاملSpreading and power allocation for multiple antenna transmission using decorrelating receivers
We propose a new scheme for multiple antenna transmission in the context of spread-spectrum signaling. The new scheme consists of using shifted Gold sequences to modulate independent information on the multiple antennas. We show that this strategy of using multiphase spreading (MPS) on different antennas greatly improves the throughput over currently known spread-spectrum multiple-antenna metho...
