Music was made popular through the modern mass media. Nonetheless, if a period of high standard performances and appreciation by a minority of culture connoisseurs can be qualified with the expression "gentrification of culture", then a period when anyone can access culture through the mass media can be qualified with the terms "popularization of culture" and in this period the reorganization of performance culture can only be driven by the public. In fact, the Jabga, which is a type of traditional song that received strong public adhesion by means of phonograph records and radio broadcasts at the time, stands as a typical example to it. Gagok and Sijo up until the 1920s and even the 1930s are believed to engage actively in the changing media environment and the new modes of music enjoyment and transmission. The Album recording of faster rhythm music and the inclusion of the Sijo, Jabga, and folk songs in one broadcast programme can be seen as reflecting such an effort. However, it can only be hard for the Sijo and Gagok to challenge the predominance of the Jabga which made its lyrics more popular and the new songs written in accordance with the new media environment. Until the 1930s in this changing environment of music enjoyment, Gagok and Sijo performers rather sought to distinguish themselves from the existing popular song style by reproducing traditional forms. The album recording and broadcasting of Lee Wangjik Aakbu, the beginnings of local singers, the participation of male performers not only contributed to the diversification the enjoyment culture of songs and sijo, but also made the 'difference in standard' with the popular songs even more salient.

본 논문에서는 기존라디오(primary) 네트워크와 스펙트럼을 공유하는(spectrum sharing) 인지라디오(cognitive radio) 네트워크에서 비재생적(non-regenerative) 다중안테나 중계 (relay) 시스템을 위한 소스(source) 및 중계기 프리코딩(precoding) 기법을 제안한다. 제안된 기법은 소스와 중계기 프리코딩 행렬의 최적해를 구하기 위해 QCQP(Quadratically Constrained Quadratic Programming) 문제를 통해 구한다. 제안된 기법은 기존라디오 수신기에서의 간섭세기 제한을 만족하면서 낮은 MSE(Mean squared error)와 높은 MI(Mutual Information)를 달성함을 모의실험결과를 통해 보인다. 또한 아주 빠른 속도로 최적해로 수렴함을 보이고 있다.

디지털 라디오 수신 환경에서 권역을 이동하거나 수신 신호가 미약한 구간 특히 실내로 이동을 하고자 할 경우 서비스를 자동으로 연계해 줄 수 있는 서비스 연계(service following) 기술이 필요하다. 본 논문에서는 하이브리드 라디오 환경에서 자동으로 서비스 연계가 가능한 방법을 제안하고자 한다. 구체적으로는 서비스 연계 이벤트가 발생할 경우 연계 대상을 단말에서 결정하는 것이 아니라 인터넷 상에 이를 처리할 수 있는 서버를 두어 청취자로부터 전달되는 위치 좌표를 포함한 관련 방송 파라미터를 제공받아 가장 적합한 연계 대상을 식별한 후 이를 다시 단말에 제공하는 방식이다.

Recently, broadcasting environment is dramatically changed due to adopt digital method in broadcasting technology. numerous country is adopting technology for converting analog to digital. However, in the case of South Korean, standard is still indefinite. In this paper, when it broadcast using DAB system, in oder to avoid interference caused by the frequency resource shortage, DAB system is substituted narrow bandwidth DRM+ system. Therefore it considers the way that solve interference. Interference analysis simulation result shows to solve high interference area in DAB environment

Recently, analog broadcasting are being converted into digital radio broadcasts, Among the various ways that HD Radio is a candidate for the U.S. approach, Digital Radio will transmit a digital signal to existing analog FM/AM. It provides clear sound quality, traffic information, weather information and various value-added services. In addition, the converted digital radio will be able to meet demand to growing demand for analog FM. In this paper, Digital FM Radio system in the same frequency band using electric field strength of the received digital radio broadcasting interference effects were analyzed. And Digital FM Radio Receiver interference effects were analyzed by interference signal power and signal power. Results were confirmed by applying equation at minimum field strength and SNR.
