This paper is concerned with the performance evaluation for the diversity decoding scheme in which space diversity technique and iterative decoding for non systematic convolutional error-correcting code are effectively combined. The concept of the diversity decoding is applied to an OFDM system (e.g. the digital terrestrial TV broadcasting system). This paper shows the performance evaluation fo...

The global migration of television (TV) from analogue to digital broadcasting will result in more spectrum bands (known as TV white space), previously used in analogue broadcasting, becoming available and unoccupied. A question is on how much white space is available and how can it be used opportunistically and dynamically without causing harmful interference to licensed users? In this paper, w...

From the perspectives of regulation and convergence, several debates on the industrial definition of smart TV service in Korean broadcasting and communications market have been in progress. The most heated controversy mainly depends on whether smart TV is controlled under the broadcasting regulations or under the communications regulations. This Korean specific problem is summarized in regulati...

In this paper we describe the potential of multi-antenna techniques (MIMO) in the context of digital video broadcasting (DVB) systems. DVB standards have been challenged by the increasing demand of high data rate applications and larger indoor coverage area. MIMO is a key technology to increase the system capacity and link reliability without any additional bandwidth or transmit signal power. T...
