DVB-T mobile diversity reception

Digital Video Broadcasting – Terrestrial (DVB-T), European standard for Digital Terrestrial Television, even designed for fixed and portable reception, offers various trade-offs between bit rate, robustness and mobile performances. Consequently, reception of DVB-T signal by moving vehicles becomes feasible under specific requirements on receiver´s side, even for all DVB-T FFT modes. The receiver must be able to cope with Doppler Effect on high-speeds as well as with path-loss in unfavorable locations. Antenna diversity is an efficient way for making mobile reception of DVB-T possible, allowing such receivers to make benefit of dual antenna reception. In this paper, general problems with mobile channel have been investigated. Also, the gain of antenna diversity was demonstrated through limited field tests in and around Belgrade, Serbia.
