Hybrid Broadcast Broadband TV (HbbTV) is an industry standard for hybrid multimedia devices that are able to combine broadcast and IPTV delivery. This paper deals with companion screen devices, companion screen applications and communication of those applications with HbbTV terminal and its applications. Companion screen devices offer additional content to user and for pleasant experience communication...
In this paper we propose a hybrid Zadoff-Chu (ZC) based pilot sequence suitable for OFDM broadcast systems. While maintaining the same scattered pilot structure and the same power level as in DVB-T2, we replace the phase values by a ZC combined sequence. This combined sequence can either carry information bits through a repetition of small ZC patterns, or serve just as a very robust fine time domain...
Broad-Band PLC like as HomePlug Green PHY (GP) and the other Narrow-Band PLC like as G3 are candidates of V2G PLC standard. These PLC candidates are different bandwidth, so they cannot coexist at the same network. Therefore, it is needed to support coexistence technology for PLC. In this paper we propose “G3-GP Dual PHY” which can be used with different bandwidth G3 and HomePlug GP (HPGP). G3 and...
In this paper, we address the problem of orthogonal frequency-division multiplexing (OFDM) channel estimation in the presence of phase noise (PHN) and carrier frequency offset (CFO). In OFDM systems, PHN and CFO cause two effects: the common phase error (CPE) and the intercarrier interference (ICI) which severely degrade the accuracy of the channel estimate. In literature, several algorithms have...
Correlative minimum shift keying (MSK), a second order polynomial modulation scheme known as tamed frequency modulation (TFM), is a constant envelope type of modulation with a perfect peak to average power ratio (PAPR), besides the property of low out of band power. We apply the linearized TFM to the single carrier transmission with frequency domain equalization (SC/FDE) concept. We then obtain a...
