Cell-Free Bistatic Backscatter Communication: Channel Estimation, Optimization, and Performance Analysis
Diluka Galappaththige, Fatemeh Rezaei, Chintha Tellambura +1
This study introduces and investigates the integration of a cell-free architecture with bistatic backscatter communication (BiBC), referred to as cell-free BiBC or distributed acce…
Time-Spread Pilot-Based Channel Estimation for Backscatter Networks
Fatemeh Rezaei, Diluka Galappaththige, Chintha Tellambura +1
Current backscatter channel estimators employ an inefficient silent pilot transmission protocol, where tags alternate between silent and active states. To enhance performance, we p…
A Design of Low-Projection SCMA Codebooks for Ultra-Low Decoding Complexity in Downlink IoT Networks
Qu Luo, Zilong Liu, Gaojie Chen +3
This paper conceives a novel sparse code multiple access (SCMA) codebook design which is motivated by the strong need for providing ultra-low decoding complexity and good error per…
An Improved EPA based Receiver Design for Uplink LDPC Coded SCMA System
Lingyun Chai, Zilong Liu, Pei Xiao +2
Sparse code multiple access (SCMA) is an emerging paradigm for efficient enabling of massive connectivity in future machine-type communications (MTC). In this letter, we conceive t…
Codeword Position Index based Sparse Code Multiple Access System
Ke Lai, Lei Wen, Jing Lei +3
In this letter, a novel variation of sparse code multiple access (SCMA), called codeword position index based SCMA (CPI-SCMA), is proposed. In this scheme, the information is trans…
Spatial Resource Allocation for Spectrum Reuse in Unlicensed LTE Systems
Rui Yin, Amine Maaref, Geoffrey Ye Li
In this paper, we study how to reuse the unlicensed spectrum in LTE-U systems while guaranteeing harmonious coexistence between the LTE-U and Wi-Fi systems. For a small cell with m…
