Optimal Non-Coherent Detector for Ambient Backscatter Communication System
Sudarshan Guruacharya, Xiao Lu, Ekram Hossain
The probability density function (pdf) of the received signal of an ambient backscatter communication system is derived, assuming that on-off keying (OOK) is performed at the tag,…
Edge Caching for Cache Intensity under Probabilistic Delay Constraint
Tachporn Sanguanpuak, Sudarshan Guruacharya, Nandana Rajatheva +1
In order to reduce the latency of data delivery, one of techniques is to cache the popular contents at the base stations (BSs) i.e. edge caching. However, the technique of caching…
Inter-Operator Infrastructure Sharing: Trade-offs and Market
Tachporn Sanguanpuak, Sudarshan Guruacharya, Ekram Hossain +1
We model the problem of infrastructure sharing among mobile network operators (MNOs) as a multiple-seller single-buyer market where the MNOs are able to share their own base statio…
On Spectrum Sharing Among Micro-Operators in 5G
Tachporn Sanguanpuak, Sudarshan Guruacharya, Ekram Hossain +2
The growing demand in indoor small cell networks has given rise to the concept of micro-operators (MOs) for local service delivery. We model and analyze a spectrum sharing system i…
Resource Allocation for Co-Primary Spectrum Sharing in MIMO Networks
Tachporn Sanguanpuak, Sudarshan Guruacharya, Nandana Rajatheva +1
We study co-primary spectrum sharing concept in two small cell multiuser network. Downlink transmission is explored with Rayleigh fading in interfering broadcast channel. Both base…
Multi-operator spectrum sharing using matching game in small cells network
Tachporn Sanguanpuak, Nandana Rajatheva, Mehdi Bennis +2
In this paper, we study a problem where multiple operators (OPs) need to share a common pool of spectrum with each other. Our objective is to maximize the social welfare, defined a…
