Picture-Based Multiple-AntennaTechnique for the DVB-T2 Receiver

Setiyanto B., Hidayat R., Mustika I. W., Sunarno

International Journal of Electronics and Telecommunications

Deep-fading can decline the quality of the received signal to below threshold, and interrupts the reception-success (generating an outage or time-out). In DVB-T2 (Digital Video Broadcasting Terrestrial Second Generation) receiver, such interruption can be identified from the displayed-picture. Multiple-antenna is one of techniques to mitigate such problem. This paper presents a multiple-antenna method for receiving the DVB-T2 signal. At any time, one of antennas is selected where the selection action is controlled by the recovered-picture. In case of using two antennas, field-measurement was conducted to collect the real data, later used in the simulation of the proposed algorithm. The result showed its capability to increase the portion of cumulative reception-success duration up to approximately 1.53 times with respect to its equivalent single-antenna.

Opracowany odbiornik promieniowania optycznego charakteryzuje się parametrami, które mogą zapewnić uzyskanie bardzo dobrych parametrów łącza. Może być zatem stosowany w łączu optycznym drugiej generacji, o większym zasięgu w trudnych warunkach atmosferycznych w stosunku do łączy obecnie oferowanych.

Elaborated optical radiation receiver is characterized by parameters which can ensure achieving of very good link parameters. Therefore it can be applied in second generation optical links having wider range in unfavourable atmospheric conditions in comparison with the ones offered at the present moment.
