The current state of digital radio broadcasting both in Russia and in the world is presented. Digiton Systems LLC carried out a high-power field trial of the DRM system in DRM Simulcast mode by order of the Russian Television and Radio Broadcasting Network (RTRN) in the FM band 87.5-108 MHz in St. Petersburg (Russian Federation) from July 2019 to December 2020. The transmitter was set to radiate at 95.9 MHz FM signal with a transmit power of 3 kW and DRM signal with a transmit power of 800 W simultaneously. The article presents the results of these studies. The results of evaluating the electromagnetic compatibility of FM and DRM broadcasting formats are also described.

Advances in wireless communications have enabled various technologies for wireless digital communication. In the field of digital radio broadcasting, several specifications have been proposed, such as Eureka-147 and digital radio mondiale (DRM). These systems require a new spectrum assignment, which incurs heavy cost due to the depletion of the available spectrum. Therefore, the in-band on-channel (IBOC) system has been developed to work in the same band with the conventional analog radio and to provide digital broadcasting services. This paper discusses the function and algorithm of the high definition (HD) radio frequency modulation (FM) digital radio broadcasting system. Content includes data format allocation, constellation mapping, orthogonal frequency division multiplexing (OFDM) modulation of the transmitter, timing synchronization, OFDM demodulation, integer and fraction carrier frequency (integer carrier frequency offset (ICFO) and fractional CFO (FCFO)) estimation, and channel estimation of the receiver. When we implement this system to the field programmable gate array (FPGA) based on a hardware platform, both theoretical and practical aspects have been considered to accommodate the available hardware resources.

The new digital radio system DAB (Digital Audio Broadcasting), developed within the Eureka 147 project is a very innovative and universal multimedia broadcast system that has the potential to replace existing AM and FM audio broadcast services in many parts of the world in the near future. DAB employs coded OFDM technology that enables it for mobile reception and makes receivers highly robust against channel multipath fading effect. In this paper, we have analyzed the bit error rate (BER) performance of DAB system conforming to the parameters established by the ETSI (EN 300 401) using frequency interleaving and Forward Error Correction (FEC) in different transmission channels. The results shows DAB to be suitable radio broadcasting technology for high performance in mobile environment.

Objektif kajian ini adalah untuk meneliti perkembangan transformasi industri radio di Radio Televisyen Malaysia. Kajian yang menggunakan kaedah kualitatif menerusi analisis terhadap dokumen kajian; (1) Pembangunan dan Perkembangan Penyiaran Radio Digital di Malaysia: Satu Kajian Kes di Radio Televisyen Malaysia; dan (2) Analisis Implikasi Perkembangan Industri Radio dari Era Penyiaran Konvensional ke Era Penyiaran Digital: 1996-2016.Transformasi penyiaran radio konvensional global tidak terhasil secara sendiri. Ia terhasil daripada fenomena digitalisasi dan dibentuk oleh senario industri media. Senario industri media mempunyai hubungan yang signifikan dengan ekonomi dan politik sesebuah negara. Setiap perubahan yang berlaku terhadap penyiaran radio dibuat adalah berasaskan kepada dasar dan perancangan sesebuah negara. Perancangan pendigitalan industri radio di Malaysia telah dimulakan seawal tahun 1997 oleh Radio Televisyen Malaysia. Langkah tersebut diambil selaras dengan Dasar Telekomunikasi Negara dan Dasar Pembangunan Nasional. Bagaimanapun, terdapat jurang pendigitalan yang ketara antara badan penyiaran nasional dan swasta. Hasil analisis mendapati bahawa badan penyiaran nasional itu mempunyai visi dan misi yang jelas mengenai pendigitalan radio, namun pelaksanaan kepada perancangan tersebut berhadapan dengan pelbagai kekangan dan cabaran. Ia menjadikan usaha pendigitalan radio free-to-air di Malaysia sebagai sesuatu yang tidak pasti.   The objective of this study is to examine the development of radio industry transformation in Radio Televisyen Malaysia. This study uses qualitative methods by analysing research documents; (1) Development of Digital Radio Broadcasting in Malaysia: A Case Study in Radio Television Malaysia; and (2) Implications analysis of Radio Industry Development from the Conventional Era to Digital Era: 1996-2016. The transformation in global conventional radio broadcasting did not happen on its own. It resulted from the digitalisation phenomenon and shaped by the scenario in the media industry. The scenario in the media industry has a significant relationship with the economy and politics of a country. Every change that occurs in radio broadcasting is made based on the policies and plans of a country. In Malaysia, Radio Televisyen Malaysia has started their plan for digitalisation in radio as early as 1997. The action is taken in line with the National Telecommunications Policy and the National Development Policy. However, there is a significant digitalisation gap between national and private broadcasting bodies. The result shows that the national broadcasting body has a clear vision and mission on radio digitalisation; however, its implementation faces various constraints and challenges. It makes the digitalisation of free-to-air radio in Malaysia uncertain.
