The development of ultra low power wireless sensors for customized wearable medical devices requires patient specific information for the evaluation of the on-body communication channel. Direct measurements on human subjects are impractical for many applications. In such cases, numerical techniques for electromagnetic analysis, such as Finite Differences in Time Domain (FDTD), is an attractive alternative...
Advances in micromachining technology can facilitate the integration of SAW (Surface Acoustic Wave) devices and CMOS circuitry on IC scale substrate for Monolithic fabrication. The optimal design and performance of these filters can be reached by using new Smart materials. The key component in the structure of the SAW device is the piezoelectric materials used which depends mainly on some important...
Recently, the attentions of communication societies are paid to MIMO-OFDM systems. In this paper we propose a new beamforming method to the receive end of MIMO-OFDM systems. To make the method work with fewer known OFDM symbols, oversampling samples are employed and multistage decomposition based on orthogonality of sub-carriers of OFDM signal is used to formulate the beamforming weight vector for...
