Fabrication and characterization of PDMA inductors

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
Integration of inductors onto a silicon chip is the main challenge in realizing monolithic dc-dc converters. Planar spiral inductors can be fabricated with top metal layer of any standard CMOS IC process. These inductors have high series resistance due to low thickness of the metal layer.

Downlink PDMA in the Heterogeneous Network

2017
Non-orthogonal multiple access (NOMA) is considered as a promising multiple access technology, which could satisfy various incremental requirements of the coming fifth generation (5G) mobile communication system. As a novel NOMA scheme based on the joint design of the transmitter and receiver, pattern division multiple access (PDMA) could enhance ...

Joint Pattern Assignment and Power Allocation in PDMA

2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017
Pattern Division Multiple Access (PDMA) is a novel non-orthogonal multiple access scheme proposed to meet the diverse demands on high capacity and large number of connections in the fifth generation (5G) wireless networks. PDMA uses the characteristic pattern to define the sparse mapping from data to a group of resources, and the sparsity of the ...

PDMA: A Probabilistic Framework for Diversifying Recommendation Lists

2015
In this paper, we derive a probabilistic ranking framework for diversifying the recommendations of baseline methods. Unlike conventional approaches to balance relevance and diversity, we produce the diversified list by maximizing user’s current marginal aspect preference, thus avoiding the hyperparameters in making the tradeoff. Before diversification,

Phase Division Multiple Access (PDMA)

2015 IEEE International Conference on Electro/Information Technology (EIT), 2015
Phase Division Multiple Access (PDMA) is a coded Multi Phase Shift Keying modulation technique, where multiple users have access to the same carrier frequency through the phase constellation. In the proposed scheme, the input digital signal is mapped into a block of orthogonal codes. The encoded data, which is in orthogonal space, modulates the carrier

Throughput Analysis of PDMA/IRSA under Practical Channel Estimation

2019 IEEE 20th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2019
Pattern division multiple access (PDMA) and irregular repetition slotted aloha (IRSA) are non-orthogonal multiple access (NOMA) protocols wherein packets are repeated across different resource elements. In this paper, first, the throughput of PDMA/IRSA is analyzed when common pilots are employed across users to facilitate channel estimation at the base
