Contribution to Synchronization and Tracking Modelisation in a CDMA Receiver
Journal of Engineering, 2013 We propose and analyze a noncoherent receiver with PN code tracking for direct sequence code division multiple access (DS-CDMA) communication systems. We employ the delay-lock loop (DLL) architectures for the tracking stage.

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 ...

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 ...

Optimal CDMA signature sequences, inverse eigenvalue problems and alternating minimization [PDF]
, 2003 This paper describes the matrix-theoretic ideas known as Welch-bound-equality sequences or unit-norm tight frames that are used to alternate minimizing the total squared correlation. This paper shows the construction of an optimal signature sequences for
