IET Circuits, Devices &Systems, Volume 2025, Issue 1, 2025.In this paper, various D flip‐flops (FFs) (DFFs) are studied and analyzed based on the performance and reliability effects of different architectures, technology, area, power, delay, and several other key performance parameters of DFFs. Based on these parameters, a few selected DFFs such as C2SFF, conditional‐bridging FF (CBFF)‐S, self‐shut‐off pulsed ...

Universal optical code division multiple access (O-CDMA) encoders/decoders
SPIE Proceedings, 2003 The ideal fiber-optic O-CDMA encoder/decoder technology should be able to simultaneously (a) select the desiredoptical bandwidth, i.e., the wavelength range of the coded signaling channel, e.g., 1500 nm to 1600 nm, to optimizeefficient use of spectrum and power to match network load needs, (b) select the spectral location and number ...

Combined source-channel coding for the transmission of still images over a code division multiple access (CDMA) channel [PDF]
Proceedings of ICC'97 - International Conference on Communications, 1998 This letter considers a combined source-channel coding scheme for image transmission over the uplink of a wireless IS-95 code division multiple access (CDMA) channel using discrete cosine transform. By adjusting the dimension of the orthogonal signaling scheme, we trade the system error-correction capability for a faster bit rate.

DDMA Signal Separation Method Based on Frame‐Interleaved Binary Mask
Electronics Letters, Volume 61, Issue 1, January/December 2025.To solve the problem of multi‐target separation failure at the same distance in empty‐band Doppler division multiple access system, we propose the frame‐interleaved binary mask method. This method can effectively separate multiple targets in above scenario. ABSTRACT Millimetre‐wave multiple‐input multiple‐output (MIMO) radar has many advantages such as

Enhance Capacity Region of Multi‐Class IIoT Network by Applying Entanglement Assistance Protocol
IET Quantum Communication, Volume 6, Issue 1, January/December 2025.ABSTRACT In the Industrial Internet of Things (IIoT) context, heterogeneous IIoT nodes need diverse performance requirements, including throughput and quality of service (QoS). These IIoT nodes transmit data over a common shared communication medium. The existing critical challenge arises in efficiently scheduling access to this shared medium among a ...
