Wideband Holographic Recorder

Applied Optics, 1974
This paper summarizes the design considerations and developmental status of a wideband holographic system breadboard designed to prove the feasibility of recording and reproducing digital data at 400 Mbits/sec and 40 Mbits/sec, respectively. The following critical system elements were investigated: multiplexer-demultiplexer electronics, linear data ...

A wideband noise suppressor for the AMR wideband speech codec

Speech Coding, 2002, IEEE Workshop Proceedings., 2003
A wideband noise suppressor for the AMR (adaptive multi-rate) wideband speech codec is proposed. The wideband noise suppressor features weighted noise estimation for an accurate noise estimate, pseudo noise injection for more suitable spectral gain, and synthesis windowing for smooth transition at frame boundaries. In the subjective evaluation with the

Rate control for wideband radios

IEEE Communications Letters, 2002
We show a technique to control the data rate emitted by wideband radio terminals. This technique is designed for adapting terminals to channel capacity variations. The proposal is based on notifying the application layer of the channel status. This information is generated by the packet scheduler, which is designed for guaranteeing appropriate channel ...

Wideband antenna and wideband bandpass filter for wearable systems

2010 International Conference on Microwave and Millimeter Wave Technology, 2010
With the rapid development in wearable systems in recent years, the need for wireless communication components integrated into clothing is increasing. Wearable antennas and radio frequency (RF) devices are faced with a considerable design challenge, especially in the gains of antennas and performances of filters.
