“…The main purpose of an on-channel repeater [5], [6], [20] is to extend the coverage of the DVB-T/H network in areas where services are inaccessible. The on-channel repeater receives DVB-T/H signal off air, amplifies it and then retransmits it on the same frequency as received.…”

“…To get identical symbol streams from all of the translators which retransmit the same transmitter signal without a distributed transmission adapter, EDTxR adopts a similar system structure of equalization digital on-channel repeater (EDOCR) [4], [5]. EDOCR is used as a repeater to fill the gap and to extend coverage area in a single frequency network.…”

“…Moreover, the newly standardized ATSC Mobile DTV Standard [3] is for a mobile television broadcasting system which inherently requires SFN for their convenient service. In many broadcasting systems including not only ATSC systems but also orthogonal frequency division multiplexing (OFDM) systems such as terrestrial-digital multimedia broadcasting (T-DMB), digital video broadcasting-terrestrial/second generation terrestrial (DVB-T/T2), and integrated service digital broadcastingterrestrial (ISDB-T) systems, on-channel repeaters or feedback interference cancellers have been actively developed and adopted for their service coverage extension and gap filling [4]- [9].…”

This paper presents a new design and implementation method of distributed translator (DTxR), termed the equalization DTxR (EDTxR), for distributed translator network in ATSC systems. EDTxR has a simple structure and does not require any devices to be added to studio or transmitter facilities already deployed. EDTxRs which retransmit the same transmitter signal can have identical output symbol streams among them without additional synchronization information by utilizing the structure of the equalization digital on-channel repeater (EDOCR). Moreover, they can synchronize output frequency among them without global positioning system (GPS) clock receivers by adopting a crystal oscillator for each translator and compensating the frequency offset of the each crystal oscillator through the carrier and timing recovery. To verify the proposed method, multiple EDTxRs are implemented and tested in the laboratory and in the field. Through the tests, it is confirmed that EDTxR is a simple and economic distributed translator for distributed transmission system which does not need additional synchronization devices. Therefore, EDTxR can be a promising translator for coverage extension of digital terrestrial television broadcasting under spectrum deficient situations.

“…Then, following several field tests, the terrestrial digital broadcasting based on the ATSC system has started from the second half of 2001, in the metropolitan area of Seoul. In addition, the use of Single Frequency Networks (SFNs) with Distributed Transmitter (DTxT) and Equalization Digital On-Channel Repeater (EDOCR) has been considered due to the lack of frequencies in the recent transition period from analog to digital broadcasting and the geographic characteristics in South Korea [1]- [5].…”

This paper presents and analyses field test results of the Enhanced-VSB (E-VSB) system proposed by Zenith/ATI and adopted as an Advanced Television Standard Committee (ATSC) standard. The possibility of successful reception at outdoor and indoor test points according to types of antennas, noise margin, and ease of reception are measured to analyse performance improvement of the E-VSB system. Verification of backward compatibility between the E-VSB and conventional 8-VSB systems, selection of test points, and configurations of the transmitter and the test vehicle are also presented. The field test results show that the E-VSB system does not only outperform the 8-VSB system at severe multipath environment such as indoor reception, but also is fully backward compatible with it.
