To realize stable live-TV transmission from mobile, a digital 800 MHz FPU (Field Pick-up Unit) using OFDM (Orthogonal Frequency Division Multiplexing) modulation scheme has been developed. The results of the field trials in Kyoto show that the OFDM-FPU is a powerful tool for the live-TV transmission of marathon races. In this paper, transmission characteristics of the OFDM-FPU are presented with operating conditions. Relationship among the field strength, the bit error rate and the delay profiles are also discussed.
