Provisioning quality-of-service to energy harvesting wireless communications
Energy harvesting (EH) is an innovative way to build long-term and self-sustainable wireless networks. However, an inconstant EH rate may have an adverse effect on the quality-of-service (QoS) of wireless traffic, such as ...
Average transmit power of adaptive ZF very large multi-user and multi-antenna systems
In this paper, we investigate adaptive zero-forcing uplink transmission for very large multi-user multi-antenna systems in Rayleigh fading environments. We assume that the number of antennas at the base station (denoted ...
A 14-mW PLL-less receiver in 0.18-μm CMOS for Chinese electronic toll collection standard
The design of a 14-mW receiver without phase-locked loop for the Chinese electronic toll collection (ETC) system in a standard 0.18-μm CMOS process is presented in this brief. Since the previously published work was mainly ...
Quasi-orthogonal space-frequency coding in non-coherent cooperative broadband networks
So far, complex valued orthogonal codes have been used differentially in cooperative broadband networks. These codes however achieve less than unitary code rate when utilized in cooperative networks with more than two ...
Multistandard analogue baseband filters for software-defined and cognitive radio receivers
Analogue baseband filters are an important circuit for channel select and anti-aliasing in wireless and mobile communication systems. For software and cognitive radio, they must be widely tunable and reconfigurable to ...
A Systematic Study of the Behaviour of PMEPR in Relation to OFDM Design Parameters
The design of systems with enhanced quality of service (QoS) and improved power efficiency has evolved into an intensive research area in wired and wireless communications engineering. Orthogonal frequency division ...
