The DVB-T2 standard is a very flexible system with a wide range of adjustable parameters. Moreover, within its main profile, another specification is defined, marked as DVB-T2-Lite. It is based on the same digital TV (DTV) system as the DVB-T2, but is more oriented on the mobile and portable TV scenarios. This paper deals with exploration of the DVB-T2-Lite profile using spatial diversity technique...
In this work, we investigate the spatial diversity gain offered by on-body channels in indoor environments. Narrowband on-body channel measurements are conducted in a dual-link topology, to cover various scenarios with different link geometries and body movements. Cooperative dual-link communications with equal-power allocation scheme are evaluated based on the channel measurements. The simulated...
In this paper, we propose an asymmetric diversity modulation (ADM) scheme for a single-source relay system that utilizes the relay's higher transmission ability as a form of diversity. To achieve this, the proposed method transmits multiple source bits over a high-order modulating relay as a way to provide additional time diversity. The spatial and time diversity then undergo 'bit'-based combining...
Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the relay chooses to cooperate only if the source-destination channel is of an unacceptable quality. In our study, we consider a regenerative relay in which the decision to cooperate is based on a signal-to-noise ratio (SNR)...
