Two-bit hybrid beamforming for broadcasting
2016 24th Signal Processing and Communication Application Conference (SIU), 2016In this paper, a hybrid system consisting of analog and digital beamformers is proposed to reduce the hardware complexity of full digital beamforming. In analog beamforming part, specially chosen two-bit radio frequency (RF) phase shifters are used.

Energy-Efficient Hybrid-RAM with Hybrid Bit-Serial based VMM Support
Proceedings of the 2021 Great Lakes Symposium on VLSI, 2021This work presents HRAM, a SRAM-based hybrid memory bit-cell for energy-efficient in-memory computing purpose. The HRAM bit-cell consists of conventional 6T-SRAM for static data storage, and extra one accessing transistor and capacitor for caching data temporarily then conduct the computation within the HRAM array.

A comparative study of hybrid bit over roller cone and PDC bits
i-manager's Journal on Mechanical Engineering, 2023Early hybrid drilling concepts date back to the 1930s, but the development of a viable drilling tool has only become feasible with recent advances in Polycrystalline Diamond Compact (PDC) cutter technology. This paper describes a new generation of hybrid bits based on proven PDC bit designs with roll cutters on the bit periphery.

Hybrid video coding for low bit-rate applications
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002This paper proposes a hybrid DCT/quadtree coding technique to compress motion compensated difference (MCD) images for video conferencing applications. The hybrid scheme is developed primarily to eliminate the visually annoying "corona" effect caused by the traditional DCT coding of subimage blocks containing edge components.

Hybrid query optimization for hard-to-compress bit-vectors
The VLDB Journal, 2015Bit-vectors are widely used for indexing and summarizing data due to their efficient processing in modern computers. Sparse bit-vectors can be further compressed to reduce their space requirement. Special compression schemes based on run-length encoders have been designed to avoid explicit decompression and minimize the decoding overhead during query ...

An energy-efficient accelerator for hybrid bit-width DNNs
2017 IEEE Symposium Series on Computational Intelligence (SSCI), 2017This paper proposed an energy-efficient accelerator for hybrid bit-width DNNs. To speedup the DNNs and make it energy-efficient, we first propose a hybrid bit-width compression method that can save the memory storage of the state-of-the-art network LeNet and AlexNet by 7x and 8x with negligible accuracy loss.

Hybrid harmonic coding of speech at low bit-rates
Speech Communication, 1994Abstract This paper presents a novel approach to sinusoidal coding of speech which avoids the use of a voicing detector. The proposed model represents the speech signal as a sum of sinusoids and bandpass random signals and it is denoted hybrid harmonic model in this paper.
