Preliminary field tests results of ISDB-Tb digital TV transmission in the VHF-high band

This paper presents preliminary results of field measurements carried out for evaluating the operation of the ISDB-T
B
standard digital TV in the VHF-high band. Measurements were performed in urban, suburban and rural areas in a medium-sized Brazilian city. The analysis includes results of static reception measurements for evaluating the received field strength and the signal to noise ratio thresholds for correct signal decoding. A comparison with theoretical values of field strength is also presented.
