This paper presents a cellular RF transmitter architecture based on a six-port modulator, and its application in an OFDM environment. This paper shows a possibility to apply RF transmitter based on six-port modulator to an OFDM environment, and also it shows that previous works which were limited to single-carrier transmission can be extended to multi-carrier transmission application. The proposed...
As the MIMO processing gets popular in LTE wireless mobile communication, the number of RF chains of base station for MIMO processing gets increased, which results in the increase of cost and the volume of eNodeB base-station. In order to solve this problem, the beamspace MIMO RF Antenna has been proposed. The advantage of Beam-space MIMO RF Antenna is to reduce the RF chain which results in the cost...
This paper reports thermal analysis of a 35kW wireless power transfer (WPT) pickup module to keep the system's efficiency at different temperatures. Temperature effects are first considered by looking at change in efficiency of the system which is influenced by change in resistance and capacitance at different temperatures. Then, we introduce methods to improve the overall performance of a high powered...
