Backscatter-NOMA: A symbiotic system of cellular and Internet-of-Things networks

Q Zhang, L Zhang, YC Liang, PY Kam - IEEE Access, 2019 - ieeexplore.ieee.org
Non-orthogonal multiple access (NOMA) is envisioned as a key technology to enhance the
spectrum efficiency for 5G cellular networks. Meanwhile, ambient backscatter communication …

Maximum likelihood carrier phase recovery for linear suppressed-carrier digital data modulations

P Kam - IEEE Transactions on Communications, 1986 - ieeexplore.ieee.org
The problem of ML estimation of the Phase of a general data-modulated carrier is considered.
The shortcomings of current iterative approaches to the problem are pointed out, and the …

Decision-aided carrier phase estimation for coherent optical communications

S Zhang, PY Kam, C Yu, J Chen - Journal of lightwave technology, 2010 - opg.optica.org
We analytically studied the block length effect (BLE) of decision-aided maximum likelihood (DA
ML) carrier phase estimation in coherent optical phase-modulated systems. The results …

MAP/ML estimation of the frequency and phase of a single sinusoid in noise

H Fu, PY Kam - IEEE Transactions on Signal Processing, 2007 - ieeexplore.ieee.org
The problem of estimating the frequency and carrier phase of a single sinusoid observed in
additive, white, Gaussian noise is addressed. Much of the work in the literature considers …

Optimal detection of digital data over the nonselective Rayleigh fading channel with diversity reception

PY Kam - IEEE Transactions on Communications, 2002 - ieeexplore.ieee.org
Based on the criterion of minimum symbol error probability, an analysis is made of symbol-by-symbol
detection of a sequence of digital data transmitted using linear suppressed-carrier …

Reception of PSK signals over fading channels via quadrature amplitude estimation

P Kam, C Teh - IEEE Transactions on Communications, 1983 - ieeexplore.ieee.org
We consider here a new approach to PSK signal detection over a slow nonselective Rayleigh
fading channel which does not require a carrier recovery loop. The receiver achieves …

An adaptive receiver with memory for slowly fading channels

P Kam, C Teh - IEEE transactions on communications, 1984 - ieeexplore.ieee.org
We consider the problem of designing an adaptive receiver with an M -bit memory for binary
orthogonal signaling over a slowly fading Rayleigh channel. Both the cases of decision-…

A robust GLRT receiver with implicit channel estimation and automatic threshold adjustment for the free space optical channel with IM/DD

T Song, PY Kam - Journal of lightwave technology, 2013 - ieeexplore.ieee.org
Atmospheric turbulence and pointing errors cause intensity fluctuation of free space optical
communication signals and impair link performance. Several receiver structures which could …

Outage probability of Rician fading relay channels

Y Zhu, Y Xin, PY Kam - MILCOM 2006-2006 IEEE Military …, 2006 - ieeexplore.ieee.org
In this paper, we consider the decode-and-forward (DF) relay network system over Rician
fading channels. We derive an analytical expression for the outage probability of the highest …

Performance of laser inter-satellite links with dynamic beam waist adjustment

T Song, Q Wang, MW Wu, PY Kam - Optics express, 2016 - opg.optica.org
In this paper, we propose the idea of dynamic beam waist adjustment for laser inter-satellite
communications, and study the performance of this dynamic-beam scheme. The beam waist …
