We have been studying a macrodiversity system that can receive transmitted signals effectively without outage in mobile relay broadcasts of road races. We conducted outdoor experiments on macrodiversity reception of the OFDM signal using four reception points set on three base stations located around an actual race course. The reception performance of selection macrodiversity (SEL-MD), (4, 2) minimum mean square error-macrodiversity (MMSE-MD), which selects two diversity branches from four ones and combines their signals, and (4, 4) MMSE-MD, which combines four signals, was evaluated using cumulative distribution probability of output modulation error ratio (MER). Consequently, the MMSE-MDs showed better reception performance than SEL-MD, and robust transmission was confirmed to be achieved in the condition that received power differs largely among diversity branches. Furthermore, it was confirmed that the reception performance of (4, 2) MMSE-MD did not degrade even when the switching between branches was delayed largely, while the one of SEL-MD degraded. |
