Abstract

In Japan, digital terrestrial television broadcasting based on OFDM is rapidly diffusing. One segment broadcasting ISDB-T has launched for mobile reception of digital television broadcasting and various services are expected. This paper discuss the cooperative reception scheme of digital TV broadcasting. The received signal after the symbol decision is exchanged between terminals and reception process is returned by using exchanged information. The optimum weight is derived from the noise distribution of exchanged signal for the maximum ratio combining.
