[Memorial Lecture] tudies on the Mobile Reception Performance and the Transmission Method of FEC Block in the Next Generation Terrestrial Broadcasting

Abstract (in Japanese) (See Japanese page) 
(in English) NHK is conducting research on the next generation terrestrial broadcasting. The proposed specification for the next generation terrestrial broadcasting has been designed based on segmented OFDM to transmit the signal for fixed reception and mobile reception simultaneously on one channel. It has variety of transmission parameters such as modulation level and coding rate, etc. Especially, Scatterd Pilot (SP) pattern can be set according to the service such as mobile reception and fixed reception. Furthermore the proposed specification also incorporates the new OFDM signal structure and the latest technologies in order to get spectrum utilization efficiency higher than ISDB-T (Integrated Services Digital Broadcasting - Terrestrial). As an example LDPC codes have been used for the proposed specification as forward error collection (FEC). The error correction capability of LDPC code can be improved by increasing a code length. However, it would be difficult to set the number of data bits in an OFDM frame to an integer multiple of a long code length.
This paper describes the consideration of recommended SP pattern for mobile reception and the transmission method for LDPC code block. We evaluated the reception performance with five kinds of SP patterns under mobile reception environment. Furthermore we propose FEC pointer to inform the decoding position to the receiver and we evaluated the reception performance of the FEC pointer transmission.
