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...
Rate control is crucial in controlling compression bitrates for video encoding. However, most rate control algorithms are heuristic, meaning that they are suboptimal and susceptible to get stuck into local optima. In this paper, we conduct a trial research which applies genetic algorithms to video rate control. Experimental results show that the proposed genetic rate control algorithm works well and...
In this paper, we consider a new channel probing scheme for opportunistic scheduling in the uplink of orthogonal frequency division multiplexing (OFDM)-based wireless systems. To reduce signaling overhead for the probing, we consider a two-step channel probing process; called pre-probing and mainprobing. Good subchannels are first estimated through the pre-probing process using a probing signal transmitted...
