A New Uplink Channel Estimation Architecture for Massive MIMO Systems with PDMA

2019 IEEE 13th International Conference on ASIC (ASICON), 2019
Massive multiple input multiple output (MIMO) with millimeter-wave (mmWave) techniques is favored by next-generation communication systems for its higher data rates, and higher spectral energy efficiency. Considering the dual-wideband effect existing in the large-scale antenna arrays, a new architecture for uplink (UL) channel estimation based on path ...

Pattern division multiple access (PDMA) for cellular future radio access

2015 International Conference on Wireless Communications & Signal Processing (WCSP), 2015
This paper presents a pattern division multiple access (PDMA) concept for cellular future radio access (FRA) towards the 2020s information society. Different from the current LTE radio access scheme (until Release 11), PDMA is a novel non-orthogonal multiple access technology based on the total optimization of multiple user communication system.

Three Dimensional PDMA Assembly: Design, Process, and Applications

Microelectromechanical Systems, 2002
This paper discusses a recent three-dimensional assembly process called the Plastic Deformation Magnetic Assembly (PDMA) method. The PDMA method allows three dimensional micromechanical structures to be realized efficiently using surface micromachining and wafer-scale, post-sacrificial-release assembly. We will discuss the principle of the PDMA method,

PDMA-1: chaotic communication via the extended Kalman filter

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1998
A method of synchronizing two chaotic systems by implementing an extended Kalman filter (EKF) as part of the receiver is presented. Communication is accomplished by parameter modulation in the transmitter and parameter estimation in the receiver filter and tolerates nontrivial parameter mismatches as well as additive noise.
