Digital-video-broadcasting-terrestrial (DVB-T) systems affected by in-channel interference are dealt with here. Attention is mainly paid to the experimental assessment of the video quality perceived by the end user when only in-channel interference degrades the transmission path. To this aim, a number of experiments are conducted through a proper testbed, which enlists a flexible DVB-T broadcasting...
Coexistence issues between IEEE 802.11b (Wi-Fi) wireless communication networks and IEEE 802.15.4 wireless sensor networks (WSN), operating within the same 2.4 GHz ISM-band, are hereinafter assessed. In particular, meaningful experiments performed through a suitable testbed and a cross-layer measurement approach are presented. Such experiments are executed both at physical layer, through measurements...
Digital Video Broadcasting Terrestrial (DVB-T) systems affected by in-channel interference are here dealt with. Attention is paid to the assessment of the effects the interference produces, especially in terms of video quality perceived by the end user. To this aim, a number of experiments are conducted through a proper testbed, which enlists a high performance measurement apparatus, a flexible DVB-T...
Cross-layer relationships among three different levels of a DVB-T broadcasting system are investigated. In particular, the "modulation layer", the "physical layer" and the "end user layer" are considered and the following parameters are analyzed and compared: modulation error ratio (MER), power intensity at the receiver connector and video quality metric (VQM) indices...
